Both designs appear to offer similar performance in aggregate, although there are differences for particular functions. I haven't yet had a chance to test the performance of the CPS variant, although Oleg has indicated he expects it will be higher.
@jwlato: Do you mind creating `IterateeCPS' tree in <http://inmachina.net/~jwlato/haskell/iteratee/src/Data/>, so we can start writing CPS performance testing code? AFAICS, you have benchmarks for IterateeM-driven code already: http://inmachina.net/~jwlato/haskell/iteratee/tests/benchmarks.hs John Millikin <jmillikin@gmail.com> wrote:
I wrote some criterion benchmarks for IterateeM vs IterateeCPS, and the CPS version was notably slower. I don't understand enough about CPS to diagnose why, but the additional runtime was present in even simple cases (reading from a file, writing back out).
@jmillikin: Could you please publish those benchmarks? Thanks. -- vvv
