Greetings,
   I have a question about the TSM server process.  I know it is a
complex, multi-threaded piece of software, but does it run on multiple
CPUs simultaneously?
   On a 2-CPU Windows 2000 dedicated TSM Server for example, where TSM
is the only application running, are both CPUs kept busy by TSM?  Or is
TSM only running on one, while the other sits around doing nothing but
overseeing all the other mostly idle processes.
   And is this also true of AIX?  Does a 1-way AIX TSM server run the
same as a 2-way or 4-way with the same processor speed?

   If you can give real answer (not vague guesses, please) I would
appreciate it, and I know others would as well.  I set up a lot of TSM
servers for low-end customers only backing up 10-15 servers, and putting
in a 1-way vs 2-way server can add a few thousand bucks to the cost.  If
it really helped it would be worth it, but from what I can see in
performance monitors, it doesn't seem to be using multiple CPUs, but
that may be more from being I/O constrained than anything else.
