Networker high cpu usage 1

[bken001]

I'm running Networker 6.0 on Windows 2000 server (p3-550). I find that whenever backup is running, the cpu hovers around 60%+. Even when idle waiting for a tape, it will do that. This seems unusually high to me.

The problem is that when a full backup runs, it inteferes with other applications wanting cpu time, thus clients tend to get RPC errors. Has anyone else encountered this high cpu use?

Yes we did face this problem and I coud't find any solution. Only way appears to be to reduce the number of sessions..

I too had a similar problem. I have Legato support and called to discuss this. We were even getting crashes when too many jobs started at the same time. Legato gave us new "bineries" to fix the problem....still didn't work so in our case (problem with writing indexes) I changed some settings and now all is working fine. I would definitely call Legato as they are aware this is a problem.

Please Geenli, could you tell me what settings you changed?
I have this kind of CPU problem too...

Legato has high CPU utilization by design. If you run a lot of savesets with a lot of directives, you will notice significant CPU utilization.

I run at 100% cpu utilization during one of my more customized backups because of the number of streams and directives. The only fix is to increase the number of processors.

How many tapedrives and which kind of tapes are You running?
Networker in general needs a lot of CPU MHz's. We've used a Sun E450 having 1 GB Mem and 2 CPUs of 400 MHz serving 10 STK9840 Drives and the Server was close to death.
Now We're running a Sun V880R having 4 CPU's 750 MHz each and 4GB MEM:
This is nice ;-)
