I am not a fan of 1 Star reviews that post basic info with no context. Wordpress is a tricky beast, and when you take into account security plugins, existing caching plugins etc., it is very difficult for a relatively new plugin to perform 'out of the box' - especially performance/caching plugins. It is everyone's right to post 1 Star reviews, but seriously folks, have a bit more respect for the publishers and ensure you have read the documentation and do the prep work before going off on a rant.

So - that's my own rant out of the way ;)

My business provides both shared hosting for some clients, and dedicated Wordpress hosting for others. Shared hosting is always tricky as you are basically sharing resources with lots of other sites, and performance can suffer especially if you have a site with lots of plugins and limited Ram and I/O.

I have been looking for a performance plugin that will give my shared hosting clients a big speed boost, whilst not requiring overhead and constant checking. RabbitLoader is a dream come true for my business. So far we have tested it on 4 client shared hosting sites and the results are very impressive. Page speed and scores have improved by around 30-40% across the board. This gives us a big advantage in our SEO services, where we can offer fast loading and other SEO improvements even on shared hosting.

2 things you must do when you first activate RabbitLoader:

1. In 'Settings-General Settings', turn OFF the radio button 'Instant content change is crucial for my visitors'
2. If you have a security plugin such as WPMU's 'Defender Pro', make sure you whitelist the 3 IP addresses used by Rabbit Loader.

You then need to wait around 4 - 8 hours on average for the plugin to do its thing. It does a lot of heavy lifting behind the scenes, so be patient. Congrats to the RabbitLoader team!
