You're probably running an unregisterised build, which is going to be generating code at least a factor of 2 slower than a registerised build. You can get an up to date snapshot of 6.4.1 for Linux/x86_64 here: http://www.haskell.org/ghc/dist/stable/dist/ghc-6.4.1.20050704-x86_64-un known-linux.tar.bz2 This build is registerised, but doesn't have the native code generator. > I'm asking because I'm unexpectedly getting really bad > performance as you can see here: > > > http://felix.sourceforge.net/current/speed/en_flx_perf_0005.html > > and here: > > > http://felix.sourceforge.net/current/speed/en_flx_perf_0011.html > > These links are unstable, this one should always have > the latest results: > > http://felix.sourceforge.net/current/speed/en_flx_perf.html > > The compilation is using: > > ghc -O3 -fvia-C -optc -O3 > > which can probably be tweaked, any advice on that appreciated. I hope you're not going to conclude *anything* based on the performance of ackermann and tak! :-) Cheers, Simon _______________________________________________ Glasgow-haskell-users mailing list [email protected] http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
