Mallory, I'm in theExcellent foreign trade hosting review recommendationThe article "TheChemiCloudIt is a very good LiteSpeed host, fast, stable, customer service support is very good, very suitable for building small and medium-sized foreign trade independent station, cross-border e-commerce site.

我们很多建站客户在使用这个服务器，有不少建站群会员经我们推荐购买，效果和口碑都不错。下图是我们推荐ChemiCloud给群友的聊天记录。

His SiteGround (SG) server has 2 months left to expire, the renewal fee is expensive, plus the mobile speed of the SG website is too slow, so he plans to change the server. On Di's recommendation, he purchased a ChemiCloud server with a Black Friday discount of $36 + 2 months of free time.

For free, I helped him move his website and email to ChemiCloud, turn on Redis object caching, install an SSL certificate, set up the Cloudflare CDN and link the caching plugin. It's not working yet.Perfmatters PluginOptimizing images, JS/CSS cases, the dyno has flown!

Just relocated site, only optimized for CDN, total load time on Google speed test 1 Seconds↓:

小迪在《高速稳定外贸主机推荐》文章中分享过一个网站速度优化经历：客户使用 SiteGround 服务器 + FlyingPress缓存插件 + FlyingPress CDN (5美金/月)，手机端速度死活优化不上去，谷歌测试分数很低，下面左图。

后来听我建议换到 ChemiCloud主机，使用免费 LiteSpeed Cache缓存插件 + 免费CloudFlare CDN，优化手机端速度飞起，下面右图。

Choose the right package

Which package should I choose for ChemiCloud website building? Only put 1-3 foreign trade websites, blogs, it is recommended to choose the red box below "WordPress Hosting", this is shared hosting, very cost-effective and fully meets the needs of the vast majority of small and medium-sized websites.

如果你预算充足（1700元左右一年），网站繁重，对速度和性能要求高，建议选择下图 “Managed Hosting". This is managed hosting with much improved performance, security, stability, speed, etc. and free paid QUIC.cloud CDN + complimentary genuine Object Cache Pro Plug-in.

There are reviews that showQUIC.cloud CDNIt is currently the top three CDNs in the global speed ranking, and the speed of the website can be increased to more than 30%. Select "Managed Hosting" One of the reasons for this is because of this CDN.

We've come across some sites built with Elementor + Woocommerce + some Ele extension plugins, using a lot of Tabs widgets, and the site is code heavy."WordPress Hosting" May not be effective to use "Managed Hosting"Fits better.

Next choose a hosting package. Buy"WordPress Hosting" Host words.Suggested selection "Triennially","WordPress Turbo". Buy 3 years at once, server selection is more affordable. courtesy of ChemiCloud 45 days full refund without reason Promise, no need to worry.

No matter SiteGround, Hostinger or ChemiCloud, all shared hosting is only cheap to buy for the first time and several times more expensive to renew, so it's time to get a new server when it's due. Try to buy the longest time package to reduce the hassle of frequent server changes.

According toResource utilization policy,"WordPress Turbo" The package has the best performance, about 3 cores and 3G RAM, and has automatic virus detection, removal, and better security.

"WordPress Pro" Package performance is about 2 cores 2G RAM, 3 years price ratio "WordPress Turbo" Cheap at $36. If you're on a tight budget, go with this one.

The lower right corner of that server room location (Singapore) is based on your IP address is automatically recommended near, the following registration process can be re-selected server room location, so do not worry, ignore it.

If you buy."Managed Hosting” 主机，1网站主机，20G硬盘空间，按年付款每个月20.83美金。3个网站主机，30G硬盘空间，按年付款每个月37.50美金，很划算。

Binding Domain Name

Select "I already have a domain”，输入域名前缀和后缀 (就算域名已经绑定其它网站也没关系)，点“Use”按钮。有些域名后缀不支持，会提示“The domain you entered is not valid", enter it directly into thecom，买完联系在线主机客服改就行。

Although free to send a year domain name, Xiaodi does not recommend coveting this small advantage, because the late renewal is expensive! And the domain name of the hosting provider does not have many features, the late server deactivation of this domain name is not good to deal with. Recommended to goNameSilo Domain Name Registration.

Some domain suffixes are not supported, prompting "The domain you entered is not valid" ↓.direct inputcomJust contact online customer service to change it after you buy it.

Select Server Room Location & Purchase Add-ons

The package information will be displayed at the top and the price on the right.The price of $142.20 in the screenshot below is a Black Friday deal, so it's lower, and the price should be around $161.64 for a normal purchase.

"Server Location" Choose the closest server room to the target visitors. If you choose the United States, it is recommended to choose "Portland" in the western part of the United States, which is faster for domestic access. "Washington D.C." is in the eastern part of the United States.

"Available Addons" Just keep the defaults as shown below, no extra money to pay, does not affect use or functionality. Changing other options costs extra money and is not necessary.

2025.03.23更新：有用户反馈 "Free Let's Encrypt SSL" 免费证书选项没了，变成 “None”。其实有的，只是换了种形式，选择 “None” 就行。创建好网站后可以安装免费的自动续签证书，下面有安装免费SSL证书教程。

"Additional Services" Save the defaults as shown below and don't check the boxes! It's expensive, unnecessary, and you can buy the 2 services below at a later date.

Finally, click the orange "Continue" button on the right. Since it's Black Friday, you'll get a discount on the total price and 2 months of free time.

Create an account

界面上方会显示下图内容，Promotion 不用填写，已自动应用优惠，已是最低价格。我正在跟ChemiCloud申请5美金优惠券，能真正降低价格。这个优惠从迪亚莫佣金里面扣，相当于我们帮您支付了5美金，金额不多，略表心意。

曾经有个用户自己谷歌搜索优惠券，填完优惠券发现价格更贵，而且不算我们的推荐没有佣金，也拿不到上面提到的福利/感谢。主机客服跟我说网上的绝大部分是假优惠券，不会降低价格，只会把推荐(佣金)计入别人名下，简直是骗人+盗窃。

教程经常更新以保证注册流程一致，所以有些截图价格会对不上，忽略就行。黑色星期五注册Turbo价格≈ $142.20，平时注册Turbo价格≈ $161.64。

按下图提示填写↓。尽量refrain from使用QQ邮箱注册，可能注册不成功。有个国外主机客服跟我说QQ邮箱经常被拿来做坏事，所以会被管控、限制。

我们平时注册开梯子+使用163邮箱等普通邮箱能注册成功。有些人可能网络复杂被误判恶意访问，可能需要梯子开全局+使用企业邮箱才能注册成功。

"Payment Method"The only payment methods supported are credit card and PAYPAl. No matter how you plan to pay, it is recommended to choose "Paypal". No matter how you want to pay, it is recommended to choose "Paypal", so that you can register your account first, and then you can still choose credit card for the next payment.

This choice is because the above picture to enter a lot of information, for fear of losing the wrong credit card information and so on to refresh the page, resulting in the need to refill the information is very troublesome. Register your account first and then pay, it's a lot more stable!

下图是邮件订阅功能，建议关闭。开启的话，会收到很多广告邮件。

按上面步骤操作后，会进入主机Dashboard仪表盘，提示有个未付款账单，点击红色的大数字1查看账单付款。或者点击左侧的 “Billing” 进入账单页面也行。

After entering the "Billing" account screen shown below, click "Pay Now" button to make a payment.

Click Select Payment Method ↓ and follow the steps to complete the payment.

View Server IP Address, Nameserver, Cpanel Account, FTP Account, Binding Domain Name Methods

After logging in to the server, tap the exclamation mark with a circle in the lower right corner of the server board (below) to bring up the server information and view the IP address. The domain name resolves to this IP address and you can access the server through the domain name.

In DashboardIf you click on the round exclamation mark button on the far right side of the host, it will bring up the information panel, in which you can view the IP address, Name Servers, Cpanel login information, and FTP login information.

Binding a domain name is simple.You can change the DNS resolution of the domain name to the red boxed 3-bar resolution shown above, and it will change to the host's domain name resolution system (How to add resolution after binding?)，自动绑定域名。至于怎么改域名DNS，百度下或者问域名商客服。

You can also bind the server by adding domain name resolution, just add two A records pointing to the IP address as shown in the following figure, one with the name @ and the other with the name www.

ChemiCloud WordPress Hosting Usage/Optimization Tutorials

Read the tutorial below to understand how to use this host and how to optimize it, and leave a comment below if you have questions.

Relocation website, e-mail

If you need to relocate your website to ChemiCloud hosting, log in and visit theThis ChemiCloud Work Order URL填写工单，按要求填写资料和设置，客服24小时内会帮你把网站、邮箱搬迁到新服务器。

If you are using a SiteGround server with Secure Login Authentication (2FA) set, it is recommended that you first set help@chemicloud.com to协作员(点看教程)，省去一次邮件答复时间。一个网站只能设置一个协作员，有多个网站要搬迁的话就为每个网站设置一个协作员，协作员名字和邮箱用一样的就行。

如果你使用 SiteGround/ Hostinger等主机商邮箱，主机不续费邮箱就会被停掉，需要换。在工单表格里面选择把邮箱也搬迁过来新服务器（下图），单里记得写上所有邮箱地址和相应密码。

下面是填写搬迁工单教程，按图文字操作。

下面是Message填写方法，Subject是工单主题，输入 Migration 就行。Message是工单内容，输入下面内容就行。

下面是我们写的工单内容，仅供参考。website 括号里面填写的是要搬迁的网站网址，如果有多个网址用逗号隔开就行。如果不需要搬迁邮箱，把第二行的 “AND EMAILS” 去掉。

第三行是要求把搬迁的网站导入WP Tookit，方便查看管理。第三行要求安装并且配置好 Litespeed cache 缓存插件的 Redis对象缓存功能。一步到位，后续不需要额外开工单。

Hi,
Please help me migrate my website(xx.com, abc.com) AND EMAILS to ChemiCloud. 
Remember also help me importe site to WP Toolkit.
Also, pls help me install and set up redis object cache function in Litespeed cache plugin.
If you need any other information, please let me know.
Thank you very much.

如果需要搬迁邮箱，需要把所有邮箱的账号以及密码一起写在上方工单内容里面，并且提供邮箱 IMAP 地址(跟邮箱/旧主机客服拿)。

搬迁完网站，记得修改域名解析A记录绑定服务器IP，同时在后台安装SSL证书，以及设置下网站（看下方管理、优化网站设置板块）。

Familiar with ChemiCloud backend, functions

服务器后台登录地址: https://chemicloud.com/login，登录后默认会进入下图 仪表盘/Dashboard 界面。小莫我加了备注，一目了然。

Access to Cpanel

服务器和网站基本所有操作都在Cpanel里面，在 仪表盘/Dashboard 下图橙色标志，进入Cpanel。从这里进入Cpanel免登录，建议以后都从这里进入。

安装/搭建WordPress网站

创建服务器后，需要安装/搭建网站。先按上面步骤进入Cpanel，新服务器第一次进入会默认弹出下图界面↓，点击红色框安装WordPress。

选择网站前缀https:// (无论有没有SSL证书都选这个)，再选择域名。后面资料夹/In Directory是安装位置的意思，留空就行。

Fill in the information as shown below ↓.

显示安装中↓。

等安装完成会显示后台地址。点击下方蓝色按钮进入网站管理。

Site Administration ↓.

Contact Online Customer Service

The orange round button at the bottom right corner of the page is the online customer service, click on it and it will expand, just type something and click on the button to start chatting, the customer service will reply in 1 second. If you encounter any problems, just call the customer service.

Open and set up enterprise mailbox

Enter Cpanel and find the corresponding function in the "Email" section. Contact online customer service to get the domain name resolution records (MX, SPF, DKIM, DAMRC) of your mailbox, and then add the resolution.

更改Cpanel 语言为中文

安装后，我们先改下 Cpanel 语言。如果觉得默认的英文语言OK的话，就不用改，跳过这一步。

在上图步骤，点击顶部的Cpanel图标↓进入Cpanel。或者在Dashboard仪表盘点Cpanel图标进入，上面有教程和截图说明。

点击右上角头像，点击“Change Language”。

选择目标语言，例如中文，点“Change/更改”按钮。

Viewing Resource Usage

On the right side of the Cpanel will show the resource usage ↓, you can see that the memory has 3G, very conscientious. sg and so on servers, the most high-grade only 2G or so memory.

Install Free SSL Certificate

域名需要先绑定服务器并且解析生效，如果使用Cloudflare解析域名需要先关闭解析旁边的橙色云朵，等安装SSL后再打开，否则申请SSL安全证书会失败。

Under the "Security" section of Cpanel, find and click on "SSL/TLS Status".

If the server is bound to only one domain name, select all the contents, if there are several domain names, only check the items containing the target domain name, and then click "Run AutoSSL".

如果只有xxx.com，www.xxx.com安装SSL成功，其它安装不成功也没关系，不影响网站正常访问。

安装成功后，会显示绿色带锁圆圈↓。

Change PHP version

The default PHP version is 8.0, it is recommended to change it to 8.1 or 8.2 for better performance and speed. In the "Software" section, find and click "Select PHP Version".

The following location, select PHP 8.1, point "Apply" can be. PHP 8.1 compatibility is better, if your plugin theme are the latest version, and more detailed maintenance in a timely manner, you can try PHP 8.2, better performance.

ChemiCloud enables extensions like Memcached and Redis in this location as well, Redis is enabled by default. If you want to enable Memcached (not recommended), just check the box. It is recommended to only enableRedis, which works better with LiteSpeed.

进入WP Toolkit管理、优化网站设置

点击Cpanel左上角(下图红框)，进入WP Toolkit。这是管理和设置 WordPress 网站的地方。

1- 先启用“接管 wp-cron.php”功能。我们在《Ultimate WordPress Speed Optimization TutorialAs explained in the article, using server cron instead can greatly reduce the burden on the server while guaranteeing the page loading speed.

2- 打开下图 “搜索引擎索引” 功能，这样网站才能被谷歌等索引收录，参与排名。关闭的话，不会收录。就算你网站还没做好，不想被收录也要打开这个功能，因为怕你后续忘记了不知道为啥网站无法被索引。

网站搭建中不想被索引的话，可以在WP后台 “设置” > “阅读” 里面启用下图功能，就不会被搜索引擎索引。也可以在 Rank Math 等SEO插件中设置Noindex不索引，所以没必要关闭上图功能。

3- 点击顶部的“一个问题”，在下拉菜单中点击 “重定向至HTTPS已关闭”，弹出文本后，点击蓝色字 “打开重定向至HTTPS”。

点击蓝色字 “打开重定向至HTTPS”↓。

跳到下图界面后，点击按钮启用就行。这会把http网址的访问重定向到https，增强安全性和SEO效果。

Although powerful, but the settings are cumbersome, set the wrong site will be a problem. Suggest searching for reliable setup tutorials, step by step operation, do not understand can be left at the bottom of the article. We have time later to write a special setup tutorial.

If you enable this plugin after the site abnormal, the optimization of JS and CSS function off on the line. CDN if you use Cloudflare, remember to link the site in this plugin.

LiteSpeed如何启用Redis对象缓存功能

有2个方法实现Redis对象缓存功能，第一个方法是安装使用 免费Redis Object Cache插件。另外一个方法是使用LiteSpeed cache缓存插件自带的redis对象缓存功能。

Method I:使用免费Redis Object Cache插件。

注意：必须先禁用其它所有所有所有缓存插件，再执行下面步骤，否则可能启用失败。

please followOfficial Redis Object Cache Enablement Guide，按步骤启用。简单的说就是在Cpanel “软件” 板块找到并且点击 “AccelerateWP”,  点击Premium下面网址最右侧齿轮。

点击启用↓。

启用后会自动在网站后台安装Redis Object Cache插件，并且自动配置好启用↓，就这么简单。记得去LiteSpeed Cache缓存插件里面禁用对象缓存功能，因为只能在一个插件启用。

如果想效果更好，可以安装我们的Object Cache Pro plugin，如果是通过我们邀请链接购买的主机，联系微信客服免费获取这个插件。

Method II:在LiteSpeed Cache缓存插件里面启用Redis对象缓存.

可以在上面启用的Object Cache插件设置里面 以及 在wp-config.php里面都可以看到host路径，填入到LiteSpeed Cache缓存插件对象缓存设置里面 (下面有教程) 保存就行。记得弄好要卸载Object Cache插件。

If you still can't read it, or are lazy, you can directly send the following text (xxx.com for your URL) to the host's online customer service, and let the other partyEnables and links the Redis cache for you, the service is that good!

Hi, my site:xxx.com, can you pls help me connect/activate the Redis in LiteSpeed Cache plugin? Thank you.

All ChemiCloud servers are LiteSpeed and can only use the LiteSpeed Cache caching plugin. This cache plugin comes with object caching, which is recommended to be enabled and helps a lot.

Enter the Host path (the black background path you saved in the previous step) as shown below, enter 0 for Port, and enter 0 for Redis Database ID as well. if a second site on the same server.Enter 1 for the Redis Database ID, 2 for the third site, and so on, otherwise the site will be abnormal.

Finally, click Save, under normal circumstances Connection Test: will show Passed, which means enabling Redis object caching is successful. The following path is different from the one above because the screenshot is from another client's website, so ignore it.

For the Redis Database ID, enter 0 for the first site and 0 for the second site.Enter 1, the third site enter 2, and so on.

If your site is on the large side, has a lot of dynamic data or a lot of visitors, it is recommended to switch to theObject Cache Pro plugin, , ,more effectiveThe LSC plugin has a lot more features and finer control. Simple small sites continue to use the LSC plug-in object caching function on the line.

LiteSpeed Cache缓存插件Crawler爬虫功能如何启用？

Crawler/爬虫功能，其实就是Pre-caching功能。爬虫会遍历网站，为没有生成缓存或者缓存已过期的内容生成缓存。好处是能尽量让所有内容处于被缓存状态，访客访问直接提供缓存不用回源，加载速度快，服务器压力小。

Crawler/爬虫功能会占用很多资源，导致网站卡顿，所有主机商的LiteSpeed Web服务器默认禁用这个功能，只有主机商才有权限开启。ChemiCloud不允许Wordpress主机启用这个功能，Managed主机可以启用。

没有这个功能的话，平时页面不会被缓存，需要前端有访客或者爬虫爬取才会生成缓存。提交谷歌收录等，或者面向AI开发网站，会有助于更多页面及时生成缓存。

可以实用第三方插件或者Cron计划任务来实现预加载缓存，详细方法这里不展开说明，请移步谷歌。

LiteSpeed Cache缓存插件CDN使用说明

ChemiCloud WordPress主机（低于10美金一个月的主机），LiteSpeed Cache缓存插件里面有个CDN设置，使用的是免费的QUIC.Cloud CDN 免费套餐，只有6个节点（美3+欧3），没有防火墙，很鸡肋。

如果要使用和配置这个免费CDN，参考ChemiCloud官方这篇教程.

迪亚莫建议不要使用这个免费CDN，效果很一般，建议use (sth. different)CloudFlare CDN免费套餐代替，200多个节点，带防火墙等功能，被称为赛博菩萨。

要禁用QUIC.Cloud CDN，在LiteSpeed Cache缓存插件里面禁用 (下图)。 

如果使用的是ChemiCloud 的 Managed Hosting主机↓，免费赠送企业区别的付费 QUIC.cloud CDN，每个月100GB流量，目前有82个节点。可以实现缓存HTML同时绕过动态缓存功能。

企业区别的付费 QUIC.cloud CDN 加速效果很好，带DDOS防火墙，和CloudFlare的企业级付费CDN不相伯仲，而且可以实现缓存HTML同时绕过动态缓存功能，推荐使用。

CloudFlare CDN's APO feature not working

LiteSpeed Cache caching plugin is not compatible with CloudFlare APO feature, you need to add the installation of theSuper page cache pluginOnly then. These 2 caching plugins can be used together, see the latter's official user guide for details on how to set them up.

ChemiCloud Common Problems & Solutions

以下是一些小D遇到或者收到反馈的常见问题，以及解决方法。如果有其它问题欢迎下方评论留言。如果是通过我们推荐链接购买的，欢迎联系微信客服咨询。

Successfully installed SSL certificate, the site still says it is not secure.

One of the advantages of ChemiCloud server is that the customer service is very good, second reply, and will help you deal with it even if it's not a server problem. If you have a problem, just contact customer service directly to deal with it, you don't have to mess around with it yourself.

Below, Diamo asked ChemiCloud customer service to help him check a website for SSL issues, and he said the SSL certificate was installed correctly and there was no problem.

I found that after closing the ladder software (scientific internet tool) opening the site loads normally and shows that there is an SSL certificate. After opening the ladder software and refreshing the page, it says that it is not secure and there is no SSL certificate installed. Looking at the error message in the picture below and analyzing it, it should be that the ladder is unstable or blocked or something like that.

新增网站，搬迁多个网站后，WP Toolkit 里只显示一个网站

有时候新增第二个网站，或者租新服务器搬迁多个网站过来后，在下图 WP Toolkit 里面只显示一个网站。只需手动点一下图片红色框的 “Scan” 按钮更新数据即可。

After the domain name binding server, the website sometimes can not open, but other people can open it!

A group member bought ChemiCloud hosting through Diamo invitation link, feedback said that after resolving the domain name site can not open, but his colleagues and server customer service can open. Xiaodi used the tool to check the domain name resolution found that A resolution in some areas of detection failure, some areas show a different IP address (without the use of CDN), the domain name is registered in the Aliyun.

I suggested that he check the domain name resolution, a few minutes later he sent back the following picture to me, AliCloud background prompts "free version of DNS, no overseas resolution nodes, overseas access to the domain name DNS resolution is slow, high failure rate", cracked the case, it is this problem caused.

The solution is to modify the NS record to bind CloudFlare and use its domain name resolution service, or you can use its CDN service at the same time. OrChange to the server's domain name resolution service, just can no longer use the free CloudFlare CDN.

Dee, I'm in theLatest Namesilo Domain Name Registration TutorialAs mentioned in the article, it is best to register with NameSilo and other overseas platforms for foreign trade websites and cross-border e-commerce websites, as the resolution speed is fast, and the website access speed is faster, and these problems will not occur.

网站突然打不开，提示Host Error。收到邮件说升级服务器

迪亚莫自己也用ChemiCloud主机，有个网站有天突然无法访问↓。

主机客服说它们升级服务器，速度更快，把我网站搬迁到其它机器，所以IP地址变了。如果域名是使用ChemiCloud的域名解析服务，它们会自动更新IP解析记录。

因为我使用Cloudflare，只能亲自手动更新。我不知道他们升级服务器会改变IP地址，所以没更新A解析记录导致这个问题。

之前确实有收到邮件通知我这件事↓，只是没提会更换IP。以后收到主机商的邮件，提示升级服务器，升级完注意要去看下IP地址变了没，及时更新域名A记录解析。或者主动问客服，这次升级是否会更换IP地址。

后续更新：登录Cpanle发现Wordpress Manager下面没有网站，数据没同步完成。联系主机客服发截图给对方弄，5秒弄好。

或者自己在下图WP Toolkit 里点击 “Scan” 可同步数据恢复正常。

Managed Hosting主机恢复备份数据失败

有个被推荐用户反馈，Managed Hosting 托管主机的自动备份数据无法恢复，点击恢复会提示下图错误。主机客服回复说是因为备份数据跟网站数据不在同一台主机上面。所以需要需要先手动下载备份再上传到网站主机恢复，不支持一键自动恢复。

简单的说，就是只能联系在线主机客服恢复数据，告诉他们你想恢复已备份的哪个日期的数据，主机客服会很快恢复好。迪亚莫已经跟ChemiCloud提建议，希望可以支持让用户一键自动恢复备份，等待后续。

小迪建议同时使用 UpdraftPlus Premium 等插件备份网站数据到网盘，这样是最稳妥的。服务器备份功能有弊端，如果忘记续费服务器会被删除，有时候火灾之类服务器也会出故障数据丢失。

UpdraftPlus Premium插件备份数据是自动的，可设置每日，每周，每月自动备份，还可以选择只备份哪些数据。在WP网站后台可查看所有已备份的数据，一键恢复下载很方便，可以只恢复特定数据。

备份支持各大主流网盘，免费注册Onedrive有5G容量完全够1-2个网站使用。也可以去淘宝花30元/年买 1T onedrive空间，可以备份100个网站以上。

Changed hosting site speed or not?

If the server is stuck, the website speed must be slow, but a fast server does not mean that the website speed must be fast. The actual access speed of the website is affected by many factors: distance, page volume, size of third-party resources, resource loading order/efficiency, network/CDN and so on.

Whether the site is slow or fast depends mainly on the way the site is built and post-optimization, it is recommended to check out Diamo's writtenThe Ultimate WordPress Speed Optimization Tutorial, follow the steps to optimize your website speed.

更新：有个用户反映换了ChemiCloud共享主机感觉没那么好就退了。首先不要拿CloudWays等高价机来比，ChemiCloud价格3.5~4.5美金/月，对标的是SiteGround和Hostinger。

Secondly, if you don't know how to set up optimization and build a super bulky website, the result will be the same with any server.

这个用户是因为网站搭建得太臃肿，又不懂优化，任何一家共享主机都跑不起来。

后来听我们建议换到 Rocket Host，速度起飞。Rocket主机是高端托管主机，免费使用企业级别付费的CloudFlare CDN + 对象缓存，深度优化Woocommerce，价格也贵很多。

如果你网站属于很繁杂，资源繁重，又不懂优化，Rocket主机是不错的选择，加速效果明显。嫌贵的话可以买 ChemiCloud 的 Managed Hosting主机，价格便宜些，加速效果也很明明显。
