CPU Performance Problems on VMWARE
hi

We have migrated SCO 5.0.6 into ESX4, but the VM eats 100% of the virtual CPU.

Here is top print from the SCO VM:
Code:
last pid: 16773;  load averages:  1.68,  1.25,  0.98                   02:08:41

Howto tune SCO 5.0.6 for VMware?

not sure about the SCO specifics running on VMWare but what is taking 83% system time? I cannot tell from the top output but you have two lpd processes in the run state. Is your printing daemons running properly? Can you post ps -ef?

Which process is hitting so much CPU usage?
Here is ps -ef output:
Code:

Try running this:

Code:
#!/bin/sh
ps -A -o "pid=" -o "pcpu=" |awk '$2 > 5 {print $1 " " $2}' | sort -r +1

It will list all processes using more than 5 percent cpu.

There's one process that seems out of bounds (4th column is %CPU used):
Code:
    root   390     1 95 02:48:50       ?    00:29:07 /usr/lbin/lpd -G

Check the printing configuration and log files for any oddities.

The manual implies that errors are in syslog but there is no mention of a "-G" switch to lpd.
