Pyblosxom and mod_wsgi benchmark

Running our custom pyblosxom engine with mod_wsgi and Apache disk-based cache enabled is currently providing a performance of roughly 170 requests per second as of a measurement running 50 concurrent requests and a total of 1000 requests against the index page as of 6th September 2008.

There are some potential improvements and lighttpd or a similar high performance webserver could probably beat these numbers by a magnitude of a few thousand requests. We will be likely testing such a setup in the future. In our tests, lighttpd itself can handle around 1012.06 requests per second for a FastCGI served lightweight PHP script with no database backend usage.
