Did you notice that lately.. the cdoserver seems to be slower and slower
after some time ?

At the beginning I have 4 threads (including my main)

Execute my client (load 30 000 objects). Take 31 seconds
Once it is terminated ... 7 threads (just for information)

I do that many times....(10 times)
(still have 7 threads)


After a while my performance is between 35 - 37 seconds...

If I stop it... and redo my test... I go back to 31 seconds.

Did someone experienced the same things ?

After

Simon,

We are in the phase of developing new features, as you know best ;-)
I've not turned on my profiler so far and I don't plan to do it before
we are feature-complete or experience a really severe degradation.
I don't consider a degradation from 31 secs to 36 secs severe at the moment.
7 threads instead of 4 doesn't necessarily mean they are performace
consuming zombies since they usually block somewhere in the thread pool
(which should have a hysteresis).
Of course these statements are only vague ideas and when time comes your
input is very valuable to bring characteristics to a production quality
level.

Please don't hesitate to file a Bugzilla so that we don't forget about
these things.

Cheers
