Subject: Re: Speed issue on Windows

P.S.: I have a P4/1 GB/SATA disk workstation that's dual-booted Gentoo
Linux and XP Professional, and I've got CygWin on the Windows side. If
there are some reasonable benchmarks in Ruby, I could run them with the
CygWin Ruby (1.8.4 IIRC), Curt Hibbs' One Click and the stock Gentoo
Ruby (compiled with gcc 3.4 and optimized O3 with march=pentium4). To
keep things fair, I'll stick to processor-bound benchmarks; I'm not sure
it's valid to compare NTFS with ext2 filesystems.

Anybody here have any favorite Ruby benchmarks? In the absence of any
other ideas, I'll probably do a 100x100 matrix factorization using the
standard Matrix/Mathn/Rational/Complex packages. That should give the
interpreter a pretty good workout.
