Re: [Haskell-cafe] newbie questions (read, etc., with Data.ByteString.Lazy.Char8)

666wman:

ghc -Onot -fstrictness --make Main1.hs && ghc -Onot -fstrictness --make Main2.hs && ghc -Onot -fstrictness --make Main3.hs

time Main1 < nums real 0m39.530s user 0m0.015s sys 0m0.030s

time Main2 < nums real 0m14.078s user 0m0.015s sys 0m0.015s

time Main3.exe < nums real 0m41.342s user 0m0.015s sys 0m0.015s

still, i'm going to google up strictness analysis to at least know what made no difference in this case ;-)

Oh, that's interesting. Did they actually recompile? (you used -fforce-recomp). Otherwise, might be an idea to use hpaste.org to paste teh Main1,2,3 source code, since I think people reading don't know what is represented in each program at this point. -- Don
