I'm testing a SAN for speed performance related to GW on SUSE. This might
not be the most accurate, but I've simply been doing this:

dd if=/dev/zero of=/grpwise/po/test.txt
dd if=/grpwise/po/test.txt of=/dev/null

and checking the resulting speed as a starting point. I was wondering if
anyone out there running GW on SUSE could run these commands and post back
your results for comparison (or perhaps you could suggest any simple tests
that would better emulate GW traffic).
