It sounds like your load may not be very small.
Your -t25 setting to threads does not help too much, because the number
of database connections is hard-limited to 7 in the ZODB source.
It might help to visit the debug section of the control_panel to get an
understanding of how many threads are actually being used at any given
moment. If you find that all 7 threads are being continually used
simultaneously, and your box can handle more threads (e.g. it's not CPU-
or RAM-bound already), we can probably figure out how to bump you up to
more database connection threads per client by changing the source.
This should really be a knob somewhere.
There is also a profiling facility inside Control_Panel/debug that does
some sort of automated performance compilation for you, though I've
never had a reason to use it. When it's running, it also purportedly
slows Zope down quite a bit.
Or, of course, you could always throw in another ZEO client if you're
getting hit too hard to handle the load.
I suggest that you:
1) Monitor your Zope clients' thread usages by using their debug
2) Monitor your Zope clients' general CPU and memory usages via vmstat
or top or what-have you.
Then report back your findings and we'll see if we can spot a
