Running a busy wordpress site; it might be a good idea to run wordpress cache, speeding up the loading of your site, 040 Hosting fully supports both modules;
There are 2 great plugins, where the second is much faster and for most users a good sollution:
1) WP-Cache
WP-Cache is an extremely efficient WordPress page caching system to make you site much faster and responsive. It works by caching Worpress pages and storing them in a static file for serving future requests directly from the file rather than loading and compiling the whole PHP code and the building the page from the database. WP-Cache allows to serve hundred of times more pages per second, and to reduce the response time from several tenths of seconds to less than a millisecond.

2) WP-Super-Cache
This plugin generates static html files from your dynamic WordPress blog. After a html file is generated your webserver will serve that file instead of processing the comparatively heavier and more (resource) expensive WordPress PHP scripts
