Hi
We did a load test of Cocoon 2.0.1 with "ab" from Apache.
Everything is fine when we do Concurrency 1 or 3
(ab -n 100000 -c 3)
and performance looks good (pretty much the same as Zope).
But when we set Concurrency 10 we run into trouble.
Cocoon seems to stop running after a certain time and is throwing
various Exceptions. And it doesn't recover (to recover we have to
restart Tomcat).
But Tomcat is still running perfectly althought Cocoon doesn't work
anymore.
So I guess it must have something to do with Caching in the memory!
Any help is very much appreciated.
Thanks
Michael
