Perhaps you could contact Jim.
Leave Jim alone he’s fixing the server!!!! al baby’s got the manual out!!!
The problem is that the server has to serve the entire page each time.
Most of the other sites have gone to html blocks so that the blocks are queued in a cache and don’t have to be reserved.
This enabled you to set up proxies to serve up the cached html blocks enabling the server to boost it’s performance since it is only serving the new html blocks and not whole pages.
Currently the Index and Comments are all one continuous html block that can’t be cached effectively.
