Following Lennart Augustsson's improvements of the Haskell implementations of
my ray tracer language comparison:
I thought I'd share the performance improvements offered by Lennart's new code
with the latest release of GHC. Time in seconds to run the five versions on
my Athlon64 X2 2.2GHz running 64-bit Debian Lenny:
So 6.8 is up to a third faster!
The fastest implementations in other language run at around 4s, so Haskell has
gone from being 3x slower in the previous implementations with GHC 6.6 to
only 50% slower with the new implementations and new GHC.
