I downloaded ghc 4.04 and ran the same test on a 500MHz Pentium-III
Linux System, and got the following figures:
Language Compiler version Options Time
Haskell ghc 4.04 -O2 8.5 seconds
Haskell ghc 4.04 -O2 -fvia-c 8.6 seconds
Mercury rotd-1999-09-17 -O6 2.4 seconds
Mercury rotd-1999-09-17 -O6 --gc none 1.0 seconds
C++ egcs-1.1.2 -O3 .17 seconds
So it looks like ghc 4.04 is still a fair way behind, at least as
far as this test case is concerned.
