We are having a performance problems and are trying to get to the bottom of it. One strange thing I see when doing a strace is there are all kinds of requests for drupal files that don't exist, sometimes its just some file and other times it might be a view or something (but nothing we created a file for). Some examples:
It goes on and on like that, 100s of different files.
I don't understand why drupal thinks these files exist
I'm current running pressflow 6.22. I'm using litespeed right now but I got the same thing under apache
