Here's my setup using ZEO/ZRS:

zserver-threads 6

<zodb_db main>
  mount-point /
  # ZODB cache, in number of objects
  cache-size 20000
  pool-size 10
    server hostname1:port1
    server hostname2:port2
    read-only-fallback true
    storage 1
    name zeostorage
    var $INSTANCE/var
    # ZEO client cache, in bytes
    cache-size 100MB
    # Uncomment to have a persistent disk cache
    #client zeo1

Useful info -- I see a config setting for zserver-threads but how do you
set the pool_size ? -- in the zope.conf?  How?
