high-performance python web frameworks

[Sandy Norton]

Has anybody made a side-by-side comparison of the performance of
python-oriented web frameworks?

In particular, I'm looking to compare jython/java combinations with
pure python combos, and subject all frameworks to load-testing by
something like the open source VeloMeter(http://www.velometer.com/)

Now if only there was a pystone for web apps...

regards,

Sandy
