Blogging Roller

Rendering a weblog page at rollerweblogger.org (an Intel-based Linux box) seems 4-5 times slower than rendering that same page on my homebox (an AMD Athlon 1600 box running Windows XP). I wonder why that is. I wonder if I can improve this situation by using database connection pooling. If that does not help, I'm going to have to do some kind of page caching. 10 seconds to load a page is just not acceptible.
