What's unexpected in particular?

How many runs did you do for each setup and how did you average them?
Also, was the hardware, memory usage and processor load, excluding that used by Zope identical over the course of all runs? (common problems are doing load tests on a box that is also doing other things)

Also, what was the config? Plain Zope with FileStorage? ZEO? etc...

What do you mean by "wsgi enabled"? How does wsgi+ differ from wsgi?

The speed drop in ZPT I think is due to using Zope 3's ZPT engine in 2.10. Zope 3 has, unless someone tells me otherwise, the policy of being "slow but right" at the moment. Optimisation may be something the Zope 3 guys want to focus on once they've finished refactoring everything to death for the 7th or 8th time ;-)

I'd be interested to see how Twiddler would compare against ZPT in your 2.10 test, mail me off list if you're interested...

cheers,

Chris
