Each version of Pressflow is API-compatible with the same major Drupal version. For example, Pressflow 6 is compatible with all Drupal 6 modules. Pressflow 6 also integrates the SimpleTest system from Drupal 7 and the CDN support patch.
After a cache clear all form the interface things get really funky. Basicly a page request takes about 1 minute! After a while things normalize and the frontend starts to perform as it should again. There are some steps to increase this (load the frontpage, restart memcached, force a theme registry cleanup by visiting /admin/themes). We don't have this problem with normal drupal 6.26.
I'm having problems debugging this. I installed devel module and configured it to use xhprof on my dev server (same setup) but it shows nothing out of the ordinary, that is wall time is at most a couple of seconds not one minute or more. Please assist, as said the problem is specific to pressflow but to be fair also for this specific sites theme.
Guess this is more of a support request then an issue, however it is specific to pressflow, with vanilla drupal we don't have this issue.
For one of our sites we have this setup:
varnish apache + mod_fastcgi + php-fpm memcache php-apc pressflow 6.26
