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

[Gregory Collins]

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.
