I believe that would be different on different hardware. What architecture? – Nikolai Fetissov Dec 22 '09 at 18:21

Not really an answer but here's a useful link to Developing and Tuning Applications on UltraSPARC T1 Chip Multithreading Systems.
I was kind of hoping there was a dedicated performance counter for such stuff.
There is also dtrace that might help here. All of this is for Solaris though, I have no idea if it's applicable to SunOS. No comment on AIX.
Here's also a blog entry of a guy measuring aligned vs. unaligned Sparc memory access.
