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.

Look at the Help on the cache parameters page for more info.
