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

Hmm. How are you compiling it? Using bytestring 0.9.1.x ?
Should be fast,

Assuming you're turning on optimisations ( ghc -O2 )
