[NCLUG] Re: July 1, 2003 talk - Linux System Performance

[Eric Schwartz]

Just for kicks, I ran this on my dual-1GHz MacOS X 10.2.6 box with 
512MB RAM.
I don't know if the results are even meaningful, but I thought it might 
be fun to see what it looked like.

I assume you'll tell us how to interpret this at the talk? :)
