Poor performance on 1GHZ model with 1GB memory.

[Ayman Altounji]

A client of ours has 3 DL360 machines equally equiped with the next configuration:
Proliand DL360
2 x 18.2, 10K RPM, Ultra 3, HS drives in Raid 1 at integrated raid channel 2,
1 x Exabyte mammoth-2 and Compaq DLT 8000.
1 GB memory,
1 GHz CPU.

Under Novell we see about 46-80% Utilisation under Novell without doing nothing on the server, just plain OS, no clients. Console One is not started.

Loading a NLM takes about 20-40 seconds.

When we look at resources the Raid controller looks like it is non-busmastering and when loading data takes Utilisation very high, about 83-90%.

The tape-streamers cannot get a performance better then about 900 KB/sec. This last issue is reported under Netware 5.1 and NT 4.0.

What can be the solution and how can we get the SCSI and Raid into Busmastering mode?

Remove the MPK (Multi processor Kernel) driver NLM out of statup.ncf.
