Wordpress Performance is Garbage!
I just switched away from Mephisto for my blog (Ruby on Rails based) to WordPress but found the default install horifically slow. I switched to WP because its popular (powering 1.8% of the internet) and its coded in PHP instead of Perl (Movable Type).
The WordPress slowness can be fixed by installing WP-Super-Cache. The initial install yielded only 16.45 requests/second (on a very powerful server). After installing WP-Super-Cache performance jumps to 1587.07 requests/second.
