Yep, I didn't understand what was going on. The fast version of find-conduit was using a raw file path

Do you mean system-filepath [1]?
No. The api is ok, but performance is terrible because everything is a String. Traversing large directories in Haskell is orders of magnitude slower than it should be (unless you use posix-paths, which obviously isn't portable). I mean something that internally uses a RawFilePath on posix systems and some windows-specific thing on Windows.
I don't know how to reconcile this statement with how find-conduit was benchmarked to operate about as fast as GNU grep since it uses system-filepath. I am probably missing something important. http://hackage.haskell.org/package/find-conduit-0.4.1/docs/Data-Conduit-Find...
I'm not seeing exactly what "grep" has to do with "find"...? Did you mean to compare GNU find with "find-conduit"? Regards, _______________________________________________ Libraries mailing list Libraries@haskell.org http://www.haskell.org/mailman/listinfo/libraries
