Thanks for not cc'ing this to perf-discuss @ opensolaris.org and thereby 
kicking off a massive inter-OS flamewar ;-)

Seriously, check out the list at 
<http://www.opensolaris.org/os/community/testing/perfbench/> for a 
starting point on some tools you might use

lmbench and / or libmicro are probably good starting places for what 
you're wanting

There are a lot of factors you can't really control that are going to bias 
any tests you do though. OpenSolaris isn't buildable by non-Sun internal 
people in a non-debugging mode yet, for example, and the debugging factor 
on Rawhide changes periodically....

later,
