Do these references point to the same object instances, or are these copied as well?
They are independant copies
Is there a way to optimize this?
1. Obviously, use fewer threads. Do you have a component that otherwise benefits from many threads?
Also note that it is almost always a better use of memory to increase the cache size than the number of threads (this is the size of each cache, not the total cache size).
Are you aware of the "activity" and "cache parameters" tab in the "database management" part of the control panel?
If not, you may not be using a 2.6x Zope - there are some significant improvements in cache usage (especially under load) in these versions.
I'm working on a 2.3.x instance which I have already upgraded to 2.4.4. It soudns asif a further upgrde is reasonable. Also, the 'activity' tab is new to me (looks interesting ;), and caching settins seem to be ignored mostly until 2.6, right? Cheers Ivo -- Drs.
