There seems to be some interest Catalyst vs Rails vs Django benchmark. The older benchmark is quite old, it was done in 2007. A lot has changed since then. I am re-running the numbers once again to see what has changed. This time around the hardware is faster and the benchmark is slightly more simple. […]

Perlbal is much more configurable, it lets you add and remove nodes in a pool at runtime. This makes deploying a new version of our web application a lot easier. I have the […]

Update: See my newer post that re-evaluates the frameworks. Things have changed since then. Today I began working on a new project and decided to benchmark Catalyst and Rails for fun.
