A site we (Zest Software) made for a big customer runs on a dual-core
server, with some multithreading so it seems like there are 4
processors.  With one zeo client, only at most 25 percent of the
processing power was used.  We added a few zeo clients and saw the
processor a lot more active, probably approaching 100 % when all
clients are fully active.  A big improvement, with no additional setup
that I am aware of.  So it is automagically handled, yes.
