To davisagli and limi:

I have just integrated David's fix and released version 1.1.0 of pyprof2calltree:

1.1.0 release at pypi

diff with previous version at bitbucket.org

However I still get >= 200% accumulated stats on the dummy xml parsing example of the README.txt file of the distrib. I don't really have the time to digg in further right now so please feel free to send more feedback and or patches :)

Once I have enough validation of by users I will submit the script to the KCachegrind developers for upstream inclusion.

Just as a note, Mike (of Spitfire/YouTube) confirms that the new pyprof2calltree makes kcachegrind give him results that match his other tools, so that is probably something that should be contributed back to the project if we can.

@philikon: I mentioned the RR improvement to be easily backportable. All other changes actually require API changes, new features from CMF trunk or removal of code (Archetypes session support). Our current policy for 3.x seems to forbid the kind of changes that would be required.

Another thing to note here, is that of course all these numbers are pretty much meaningless for any real world site deployment. What they suggest is that you can lower the site rendering time by about 20ms. If your site renders in 500ms, the effect is still there but doesn't look quite that impressive.

Is there a chance of some of those speedups to make it into Plone 3.x? Maybe not the switch to Chameleon, but perhaps the other stuff.

This is a simple Plone coredev trunk checkout run with the chameleon.cfg. Benchmark is "ab -n 10 ..." against the various different targets. Nothing special at all.

Would you be willing to make your code for running...

Would you be willing to make your code for running the benchmarks public, so we can play along at home and see how different machines compare, etc? :)

Cool!

By the way I'm not trying to be secretive; you can grab the patched pyprof2calltree.py from http://wglick.org/pyprof2calltree.py
