MW> Is it possible that gcc is making use of the ppc AltiVec instructions, MW> and ghc is not? :) even C version performs only 20 millions of additions in one second because this program is most limited by memory throughput - it access to 24 memory bytes per each addition. GHC just can't produce simple loops even for "imperative" code. JHC can be much better in that area, i strongly recommend Sven to try it -- Best regards, Bulat mailto:[EMAIL PROTECTED] _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
