Re: [Haskell-cafe] Slow mvar when compiled with threaded

Here's a much simpler implementation for that sort of pattern, using channels to fan out work to threads. I added a dependency on Criterion because getCPUTime is basically useless for this kind of measurement on Mac OS X since it doesn't include the time that the process spent waiting on IO: Great, thank you very much. You gave me material for learning ;) However, my version is significantly faster when compiling without -threaded. With -threaded option, your version is much faster than mine, but both are significantly slower
