System load testing scripts needed

Craig A. Sharp — Thu, 18 Mar 2004 08:57:08 GMT

Hi all,

I am looking for scripts to perform heavy IO and CPU load testing on my HPUX and Linux systems. We have purchased a storage solution and need to load test as hard as possible.
Perl would be great but regular scripts or C is fine also.

Thanks,

Craig

for I/O testing, you can use

dd if=/dev/dsk/cAtBdC of=/dev/null

replacing cAtBdC with valid disk devices

If you run one of these for all disks on the system at the same time, you should get a resonable test.

A command I used in the past:

# cd /usr/bin
# while true
> do
> for i in *
> do
> nroff -man $i > /dev/null
> done
> done

This got a load on a uVax running ultrix to a value above 300 !!!
