You need to understand what happens near the 7th minute.
Does the memory consumption increase? [snip]
Nope....the machine is just as responsive as it was before. It is a very high end configuration... a HP bl20p blade server, 1 cpu - 1gb ram with oodles of other management paraphnelia. Hence as far as the config is concerned i am sure that it can sustain much higher workloads that sending apps for a toss so early in the test.
I observed that Zope becomes slower and slower as it takes more and more memory. I attribute this to effects of the cyclic garbage collector.
[snip] Just yest before i left for home i noticed sudden drop in hits/sec. The max i would achieve for 50 users was about 250 hits/s. But i guess i made some config changes which dropped this to <100hits/sec and about 10TPS overall. But this still isn't an excuse for the zope process to go for a toss at the 7-8th mintue of the test. We should atleast get Zope to be able to withstand to the current load if not scale lineraly to the increase in load over time. It 250+ hits/sec is not poss fine...atleast the smarto shouldn't go down. How can we force a GC on this process periodically. The GC for WEblogic works in a very simple manner cleaning up the "Stack Space" for the process once the upper limit is hit. Comments please????. Trevor
