Obviously, the target instruction set matters quite a lot. I think I’ll
be compiling my own ruby from now on.

Ok. Since I can’t possibly win this DSW, I’ll try this on my slowest

It took 42.070099 seconds to run. 23769 iterations per second.
Aaand…
- PIII 500MHz (diskless workstation with very limited RAM - especially

It took 202.375195 seconds to run. 4941 iterations per second.
(Wooot !)
BTW, on the other direction :
