The zserver-threads setting controls the number of "application"
threads; these are running handing the application (Plone in your
case) code for requests. The server itself uses a thread for handling
socket communication, reading & parsing the requests as they come in,
queuing them for an application thread, and managing the transmission
of response data. ZEO will use an additional thread for communication
with the storage server(s).
Other components may start additional threads as well, depending on
Plone and your configuration. For example, zc.monitor starts a thread
to handle monitoring interactions. Someone with Plone-specific
knowledge can probably help more.
