Re: [Haskell-cafe] File I/O benchmark help (conduit, io-streams and Handle)

Something must be wrong with the conduit "NoHandle" code. I increased the filesize to 60MB and implemented the copy loop in pure C, the code and results are here: https://gist.github.com/gregorycollins/5115491 Everything but the conduit NoHandle code runs in roughly 600-620ms, including the pure C version.

Does your workstation have an SSD? Michael's using a spinning disk.

If you're only copying a GB or so, it should only be memory traffic.
