Hi, I'm currently optimizing/analyzing a Zope server and I noticed the following: The number of references to specific objects (in this case specifically Squishdot comments) increases almost linear with the number of threads. Does this mean each thread keeps it's own cache pool of objects? Do these references point to the same object instances, or are these copied as well? I have the impression the memoryconsumption grows with the number of threads - is this true? Cheers Ivo -- Drs.
