Varnish vs. page cache graph
Heine — Fri, 31/07/2009 - 20:24
Varnish is running on the same box (lame duck edition) as Apache, and specifically configured to cache pages for anonymous users, not just JS, CSS and images. The pressflow reverse proxy patches were used to prevent sessions for anonymous users. All on Drupal 6.13.
The ab command used to build the graph includes a fake has_js cookie:
The no cache requests/seconds number decreases from about 7.2 request/s to 4.2 requests/s. A large number of requests fail if the concurrency is increased above 100 for non-varnish setups.

Forget about # pecl install apc (Alternative PHP Cache on Debian Sarge). This is going to hurt.
Alternative PHP Cache on Debian Sarge

This is a repost about a different (now defunct) server.
Khalid wrote a small guide to Installing the Alternative PHP Cache on Ubuntu Dapper and Debian. The installation on Debian 3.1 (Sarge), requires a few extra steps though.
