This set of measurements was captured by me on my old Compaq Armada E500 from
around the year 2000. It has an Intel Coppermine Pentium III running at 600
MHz with 384 MB RAM and running Ubuntu 7.10.
The benchmarks were run today (2007-12-21) using ghc 6.9.20071119 (freshly
downloaded and reinstalled) in runlevel 1 (single-user mode). I did leave
the wireless card in, which might have produced some interrupts. Still, the
quality of the timings proved to be good, with a standard deviation of at most
1.2% of the average run-time.
This run includes the hand-tweaked assembly benchmarks (as does the Athlon64
run in the next email).
Note how much less the assembler tweaks help here (until one gets down to the
wicked MMX tweaks) compared to the situation on the Athlon64 in the next mail.
They still help, though.
