You can set the log level to debug. This will log the entire ZEO
protocol. Analysis will take require a bit of work.  (Note that ZEO
3.10 no longer does this level of logging even at the debug level, as
it slowed the server down.)

You could temporarily hack the ZEO storage server code to collect
statisics. That would probably be easier than debug logging.
