RE: Priority and CPU usage of Domino Services

[steve.simpson@xxxxxxxxxxxxx]

Hi,

We are experiencing exactly the same problem.  When the Domino jobs start
the system basically grinds to a halt until the Domino jobs have completed.
This seems to get worse the more data there is in the databases.  Is there
anything I can do?

Thanks

Nathan,

Yes, this sounds like fairly normal Domino behavior.  Batch jobs will try
to consume whatever resources are needed in order to accomplish their
job.  Having a job periodically wake up and do some intense work should
not be considered a problem unless your system is approaching CPU
capacity.

If your system is approaching 100% CPU utilization and the Domino jobs
push you over the edge to the point where interactive users (or other
critical jobs) experience prolonged response times, then you have a
problem.  Are you there?

Andy Nolen-Parkhouse
