Gentoo Linux 64-bit. Aside from the 64-bit maybe, I can't make
out a good reason why the runtime should depend on the OS so
much.
Are you sure you don't run on a PC from 2000 and did you use
the compiler flags I gave on top of my post? Did you disable
CPU power saving and was no other process running at the same
time?
By the way I get very similar results when using the LDC
compiler.
