#!/fellow/monks.pl

I wrote a CPU benchmarking script (at http://www.massyn.net/?p=131) a few weeks back to compare system performance at home, with our big IBM AIX servers (just because I'm curious). I realized that using a "prime number" counter is probably not the best way to go, since primes are exponential, so the numbers being returned won't be entirely accurate.

Ok, regardless of that fact, what I did find very strange was that my cpu_bench.pl script performed much slower on a big IBM P690 Regatta (AIX 5.3) than it did on my AMD Athlon XP2600 (running XP Active State Perl 5.6).

Now here's my question : When writing a system performance script, what should I do / not do? It looks like the different versions of perl (between Windows & AIX) do things differently, or my code is just not optimized enough to handle different hardware layers. Maybe Perl just isn't the language to do this in...

What do you say, gentle monks? Have you done something similar? What can we use to determine system performance, both CPU and storage, the ability to compare my desktop with my enterprise server, to ensure I get the right level of service.

Thanks!
