Re: [Haskell-cafe] Re: How to optimize the performance of a code in Haskell?

I've not looked at the code, but you'll want ghc to do better optimizations than -O. -O2 is what you should use in general. Also, number-crunching often profits from -fexcess-precision.

also, floating-point number crunching usually faster with -fvia-C -optc-O3 -- Best regards, Bulat mailto:Bulat.Ziganshin@gmail.com
