I'm not subscribed to -performance, hence why this isn't a true reply...
I noticed that Steve said:

All the time is spent processing super-smack and only 25% on mysqld.
If you're willing to spend more time looking at this, I suggest that you
run truss or ktrace on the super-smack processes. I did a small amount of
mysql vs postgres vs firebird benchmarking two years ago for a class
project, and noticed that mysql's results were showing the same phenomena
- our test program was using more cpu than mysqld. I run truss on our
test program and found that it was doing ONE BYTE READS from the socket,
rather than something larger.
I never had the time to see if the problem was fixed at a later time or
not. You may wish to see if that same condition is still happening.
