Since we restarted are NetWare 4.11 server the utilization is high (varies from 20-80%) which is much higher than usual. We had to down it as a disk in the RAID 5 array failed. This has been replaced and the array rebuilt it but now the performance is poor. I've looked in Monitor/Processor Utilization and 'Idle Loop' takes up around 80% of the load. Anyone any ideas on whats causing this?

For info ARCserve 6.1 and ZEN 2 are installed on this server.

You want a high idle loop as that is what marks when the processor is not doing anything.

Check support.novell.com and pull up the following TIDs.
10012765
2928824
2950154

There are numerous TIDs concerning poor performance. What other applications are running on the box? backup, groupwise, betrieve, etc.

This may be unrelated but during our workstation migration from NT to W2K we had high utilization on our Netware 5.1 (SP2) boxes. We couldn't figure it out. Then we noticed that user could not see the properties of file or directories. Finally weran DSTRACE with the emu switch and tracked it down to a user's pc. The user was in Explorer and was tring to view the properties of a directory but nothing was happening. We were mapping our drives from Explorer then disconnected the drives and mapped though the red N in the icon tray. After that the users can now view the properties on folder and files and the high utilization is a thing of the past. Hope this helps I know that the high utilization on our servers was driving us CRAZY and even abended them. Good luck.
