Haskell Strings are a common performance bottleneck; for example when
serving files in the Haskell web server I avoided the conversion to
Haskell Strings altogether by reading/writing arrays of bytes (see the
paper for details).
But it sounds like in your case you need to open lots of (small?) files.
What do you do with the contents of the files?
Cheers,
