> I use 4 processes with 7 threads each for serving data
Any reason for 7 threads? Try 1 thread? Is it a classical web application? Or
you creating threads in your application?

You can change the tmp location in Python by setting TMPDIR environment variable
for your process.
I would advise against persistent disk cache and increase the ZODB
cache-size. If you
are using latest ZODB you can use the cache-size-bytes which mostly
works. You can
set it so zodb cache for each process will not exceed, say, 512MB.

If your ZEO server process is not bottlenecking - it is your application.
> Does someone see any way to ease the load?
dont know your application but it is doubtful that ZODB is your bottleneck.
