Re: [Haskell-cafe] Timing execution of individual functions in ghci?

Hi Magnus,

Given that all I'm interested in is relative timings it might even be enough to do a rough comparison of two implementations too.

Optimizations - especially in Haskell - can change the runtime behaviour quite dramatically. So comparing the runtime performance without turned on optimizations is pretty much pointless. Meaningful benchmarking is hard and adding any kind of uncertainty doesn't make it in any way easier. Greetings, Daniel
