If you’re using Movable Type, and your blog seems to be going kind of slow in speed of load time, it might be good to take a look at changing it up with FastCGI. FastCGI allows your admin side of things to run a bit faster since it turns it into a persistent account.
If you happen to be running on Dreamhost? No sweat. A slightly different version of installation will work splendidly for you too.
