I tend to use -O2, but haven't really tested it against plain -O. >From what I've seen -fvia-C is sometimes faster, sometimes slower, I tend to cross my fingers and hope the compiler uses sensible defaults on the current architecture. One thing that IME makes a difference is -funbox-strict-fields. It's probably better to use pragmas for this, though. Another thing to consider is garbage collection RTS flags, those can sometimes make a big difference. -k -- If I haven't seen further, it is by standing in the footprints of giants _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
