[Zope] Fwd: [Zope-DB] HEEELP! my zope has become virtually unusable

[Tena Sakai]

Hello Toby,

Thanks for your reply.  I looked at those number after a restart and they
now look like:

Total number of objects in the database: 10585
Total number of objects in all caches: 355
Target Size: 400
Target max time between accesses: 60

I didn't know that top two numbers were dynamic.  Since
the balance has changed, I'd like to leave them alone for
now.

Regards,

Tena Sakai

400 is objects per thread. If you have the default 4 threads (and assuming you
are not using versions) then it is interesting to note that 2294 is much
bigger than 4*400

That indicates you have memory pressure. This might be the cause of your
problem. If so, you could try:
* doubling the target size, and perhaps halving the number of threads.
* upgrading to 2.6. the cache manager was rewritten and is much better
behaved.
