WordPress is probably the most popular blogging platform on CloudFlare, with many WordPress users taking advantage of the fact that CloudFlare's free CDN can help speed up their sites by caching static content and distributing that content to CloudFlare's datacenters around the world. Because WordPress is such a popular blogging platform, I thought I would include some other helpful tips to help speed up your WordPress blog using CloudFlare and provide some other quick tips about optimizing your Wordpress site.
CloudFlare tools for WordPress users:
CloudFlare is complementary service to other caching plugins you may be using for WordPress, including W3TC (W3 Total Cache). You can even configure CloudFlare settings directly in W3TC.
If you're using plugins for services like Google Analytics, consider removing the plugin from WordPress so that CloudFlare can automatically add your Google Analytics code to all of your pages through our CloudFlare Apps integration.
Some other tips to speed up your WordPress blog:
Don't install too many plugins.
While there is no hard rule for how many plugins you should have active on WordPress, it generally seems that having no more than 10-12 active plugins is a fairly safe bet to have active. I recently saw a post online where someone had 44 plugins active on their blog, which only slows things down because each plugin is creating another call to another service.
Remove any inactive plugins.
If you're not using a plugin on your WordPress blog, remove it if you have no plans to use the plugin again.
Don't have too many social media buttons on your site.
While having social media plugins and social bookmarking options on your site is indeed important for your blog's traffic and visibility, you don't want to overload your blog with widgets and bookmarking options. Find one or two that cover the major social media services well, then remove any additional plugins.
Optimize your images
There are a number of options for optimizing and compressing images on your WordPress site. I've personally seen a number of bloggers use Smush.it to optimize the image
