Some time ago, we introduced our nightly performance graphs. This was a quick hack to allow us to see performance regressions. Thanks to Miquel Torres, we can now introduce http://speed.pypy.org, which is a Django-powered web app sporting a more polished visualisation of our nightly performance runs.
While this website is not finished yet, it's already far better than our previous approach :-)
Details about announcement on pypy-dev are found here.
If you're are interested in having something similar for other benchmark runs, contact Miquel (tobami at gmail).
Quoting Miquel: "I would also like to note, that if other performance-oriented opensource projects are interested, I would be willing to see if we can set-up such a Speed Center for them. There are already people interested in contributing to make it into a framework to be plugged into buildbots, software forges and the like. Stay tuned!"
