new figures, after updating bytestring (0.9.0.1.1 -> 0.9.1.2) && using -O2
time Main < nums real 0m2.531s user 0m0.015s sys 0m0.015s time Main2 < nums real 0m13.999s user 0m0.015s sys 0m0.015s time Main3 < nums real 0m2.796s user 0m0.015s sys 0m0.015s thats more like it, even the unpacking didn't hurt so much. the morals: "Thou shalt update your libraries" & "Thou shalt not forget to turn on optimizations" before bitching it's too slow ;-))) thx On Tue, Oct 7, 2008 at 5:19 AM, Don Stewart <[EMAIL PROTECTED]> wrote: > Hmm.
