Best I've found for a very slow server

I is hard for me to judge the effectiveness of caching plugins these days since my host (Hostmonster) has dramatically increased the throttling of my sites over the last two months (any recommendations for a good WordPress host?)

But after trying several new caching plugins (I had been using either W3 Total Cache, WP Super Cache, or Quick Cache [still a good plugin]), I have found that I am getting very good results with Lite Cache.

I am sure that it must be some sort of coincidence, because I know that a caching plugin cannot effect backend performance, but I would swear that with this plugin activated, by admin pages load much more quickly (maybe the site is actually not throttled as much when it is activated).

Thank you, Stefano, for contributing this very useful plugin to the WordPress community.
