I had not used any special compilation flag either, but just to be
sure I've recompiled a stock Ruby 1.6.8 in the same environment, and
it seems you're right, the speedup is less impressive:

ruby 1.6.8 (2002-12-24) [i686-linux]
M op/s:        2.254698905

ruby 1.8.0 (2003-08-04) [i686-linux]
M op/s:        2.64777391717631

That's a 17.5% speedup, instead of about 37% for the previous measure.
Still quite nice. The date tag of the Debian version is different
though, so maybe Debian uses a patched version, which could explain
the difference.
