Speed Up – Page Cache was constructed for made caching dead simple. Simple one-click install. That’s it.
When a page is rendered, php and mysql are used. Therefore, system needs RAM and CPU. 
If many visitors come to a site, system uses lots of RAM and CPU so page is rendered so slowly. In this case, you need a cache system not to render page again and again. Cache system generates a static html file and saves. Other users reach to static html page.
After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more expensive WordPress PHP scripts.
The static html files will be served to the vast majority of your users: 
– Users who are not logged in. 
– Users who have not left a comment on your blog. 
– Or users who have not viewed a password protected post. 
99% of your visitors will be served static html files. One cached file can be served thousands of times.
In addition, the site speed is used in Google’s search ranking algorithm so cache plugins that can improve your page load time will also improve your SEO ranking.

Purge Cache for CloudFlare is a simple plugin that uses CloudFlare® API to purge cache of full HTML pages when a new post is made.
This free version is only indended for basic usage. If you want to use it in full capacity, consider buying <a href="https://shop.milandinic.com/downloads/purge-cache-for-cloudflare-plus/" rel="nofollow ugc">premium version</a>.
It works by purging front page, post’s page, and main RSS feed. This should work for most sites. However, there are of filters, actions, and methods that provide full customizability and extensibility.
Note that this plugin also sets cache to 30 minutes for all frontend pages. This means that if you use default option in CloudFlare, it tells them to revalidate page cache after that time, so it means that cache for any page expires on CloudFlare servers after that time.
You can change this limits by using filters from you code. If you want user interface in your admin, use <a href="https://shop.milandinic.com/downloads/purge-cache-for-cloudflare-plus/" rel="nofollow ugc">premium version</a>.
You should create new CloudFlare page rules to set proper caching. It is your responsibility to set this properly.
First page rule should exclude certain paths from caching. Recommended value for this is <code>wp-</code>. This excludes admin pages and default <code>.php</code> pages. Example of URL pattern: <code>*example.com/*wp-*</code> This value can also set via filter or via admin in <a href="https://shop.milandinic.com/downloads/purge-cache-for-cloudflare-plus/" rel="nofollow ugc">premium version</a>.
Second page rule should sets caching. You need to set “Custom caching” to “Cache everything”. Recommended value for “Edge cache expire TTL” is default, “Respect all existing headers” which means that CloudFlare revalidates after 30 minutes, while for “Browser cache expire TTL” is also 30 minutes. Example of URL pattern: <code>*example.com/*</code>
