Apache is set to "MaxClients 50"
Zope.conf has set "zserver-threads 5" and
<zodb_db main>
cache-size 500
pool-size 25
...
</zodb_db>
I will note that a cache-size of 500 is ridiculously low. (Even though
old versions of Zope shipped configured like this!)
It needs to be at least 5000. Frankly, 50000 wouldn't be bad for a
large, busy site.
To optimize your cache-size param, watch the ZODB read/write graph, and
keep increasing the cache-size until (a) there's no more effect on reads
or (b) you run into memory trouble.
Of course, the optimization will slip a little as site usage patterns
change.
