You're better off installing a good caching sollution to speed things up.

I actually tought about moving away from wordpress towards textpattern a while back. Seems to serve the same amount of visitors with about 1/3rd of the server load according to some sources (granted, it was on the textpattern forum that i found these statistics).
I didn't do it in the end because i wasn't sure i would be able to convert my current sites without to much downtime.
