Try increasing the sys.setcheckinterval() value in z2.py (I think
there's a flag you can pass to z2 but I forget which one it is).   The
value should probably be your pystone rating/50, e.g. 5000 pystones =
sys.setcheckinterval(100).  The default in z2 right now is 120, I
think, which is too small for today's fastest CPUs.   An Athlon XP
2000+ (25000 pystones) should have a sys.setcheckinterval(500).


Doing this will allow each python thread more time to dispatch before
it does a lock shuffle.

<excerpt>Hello!


I have tested ZOPE under heavy load (about 100-200 users
simultaneously) and noticed that

2 zope running on 1 PC works (processing requests) faster than 1.


Zope runs under Windows XP with -t 10 options.

Test were made with RationalRobot.


What's wrong with my ZOPE installation??

Is there any performance tune tricks??


Thanks

Andrew
