[Zope] zope performance issues

[Trevor Warren]

Hey Chris,

 Yep i do accept that the client performing the test
could be at fault but that may not be the case here.

 A 20 user test load is as fishy as the rest...:D. The
test is for a duration of 15mins. Hit rate remains
constant at 150 hits/sec. Suddenly post 7th minute
Zope goes for a toss. This is really surprising. 

 Initially i was under the impression that the test
for 50 imultaenous users was taking the server down.
But now even this test for 20 uses post the 7th minute
send zope for a toss. 

 Hit rate falls from 150 hits/sec to <40hits per sec
and resp times more than quadruple. ZopeDB caching
20000 + Threads for Zope at 10 + ZODB thread pool at
10. Should i look at apache/zope mix???. Havent tried
out RaMCacheManager yet. Or whatever that was. 

Trevor
