Hi,

We are running NetWorker 6.1.3 on Win2K. We have noticed that nsrd can get
overloaded to the point of virtually hanging without the server even coming
close to it's limits.
In other words the bottleneck is networker, not the OS or the harware it
runs on.

regards
Andrew McGeorge

have 500 on a 4x400MHz Sun master with two e4500 storage nodes.  In that
environment, one cpu is pegged about 22 hours a day and nsrd is VERY much
our performance bottleneck.  Do you have any thoughts about how much
(percentage) the load dropped after moving to 7.x and the more efficient DB
style?

On a related note: a common way to load up a nsrd is to have
too many monitoring programs running at once.  nsrd responds
to all status requests from programs like nsrwatch, nwadmin,
etc., as well as initial save and recover requests.  The
windows nwadmin in particular is notorious for requesting status
from nsrd more often than it should.

Anyway, if you have a number of administrators who are all
monitoring backup performance, you are actually driving up
the nsrd load significantly.  This may not be your problem,
but it is certainly something to look at.
