CloudFlare makes security and performance for WordPress sites super simple. CloudFlare makes any site on WordPress twice as fast, protects them from attacks and makes it simple to add web apps with a single click. CloudFlare supercharges websites with no need to add hardware, install software, or change a line of code. To help WordPress blogs specifically, CloudFlare developed a WordPress plugin (http://wordpress.org/extend/plugins/cloudflare/). Additionally, W3 Total Cache, a leading performance plugin (http://wordpress.org/extend/plugins/w3-total-cache/) offers CloudFlare as an integrated option. CloudFlare also complements WP Super Cache (http://wordpress.org/extend/plugins/wp-super-cache/), a very fast caching engine.
CloudFlare is awesome for sure. Also, check out WP Minify…I like its minify caching better than WP Super cache.
Thanks!
