Sometimes you find them (and get pissed off) and sometimes somebody else finds them for you. But, you've started to talk about something I actually wonder about... How do you define these load metrics? What is a heavy load on each of the machines? Is it measured by xload, response time on some app, or what? How many users can you stick on each machine before the load becomes heavy? Religious differences and rose-colored glasses aside, what is the difference in throughput between the two platforms in the specific case of BEST? Where does SGI need to do some code tuning? I'm interested. nate
