What's unexpected in particular?
The average response time for the different types with different versions.
How many runs did you do for each setup and how did you average them?
There were a few runs for each case but I can't remember the exact
number. Every run shown similar results. The last one was picked. The
average shown is for the latest one.
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)
Hardware is detailed in the page. The box was doing nothing else
except running one zope instance at the time.
Also, what was the config? Plain Zope with FileStorage? ZEO? etc...
FileStorage with stock zope.conf except for enabling wsgi were noted.
What do you mean by "wsgi enabled"? How does wsgi+ differ from wsgi?
The wsgi directive was enabled in 2.10.0b2. Re wsgi+, do you mean in
the graphic? I need to correct that as the text was truncated. It
should be wsgi+SpeedPack and wsgi+profile.
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 ;-)
yes, i think that's the cause of the tal speedup in 2.10, but then
static content is painfully slower.
cheers,
