I love how this plugin carries a lot of the basic needs to improve your site: minifies CSS and Javascript, page cache, PHP OpCode cache, Memcached Cache, removes white space, Page Caching, but my favorite is that it keeps your site more secure in changing your wp-admin - so hackers can't log in so easy! You can do this manually, but this plugin offers so many features for free! I like how it also has the GTmetrix option so you can see what areas to improve your site. When I run Google Page Speed and GTmetrix my site score improved! I also had a few questions regarding the setup of this plugin and their support team was great! Took the time to make sure I installed it correctly! I highly recommend you try this plugin! A FEW TIPS: Create a staging site and ALWAYS test NEW plugins here - so your "live site" is never affected, remember the plugins you have already installed can SOMETIMES CONFLICT with the NEW ONES you decide to add or even your theme, and the type of hosting you currently also gets affected with plugins. I use: Divi Theme, VPS Hosting, Cloudflare CDN, and have 9 plugins with this one! Hope this helps!

This plug-in has a lot of good features built-in, but overall does a really bad job. Lately, I've had I/O and physical mem warnings. Took a look into it and it was the cron jobs causing it, but the A2 plugin actually changes the WP Cron jobs to server cron, which is a good thing because the WP Cron isn't so great, but if the server is limited to such a low memory that even it's own cron jobs cause problems, that isn't good. And they are only set to 1 per minute. Maybe this is more a hosting problem, but the plugin slows the admin down too. Everything takes way too long to load. Deactivate the A2 plugin and it works smooth. I guess I am going to have to look for an alternative. Just like having all the options in one plugin. I have fewer issues with clients that are on Gator. For the price of A2, it should be better.
