I've uploaded attoparsec-text and attoparsec-text-enumerator to Hackage. I've written those packages late last week and asked for

Very nice! I'll download this and try it out. Attoparsec has a bit different combinators than parsec so it'll take some rewriting, but it's work I'd have to do anyway to try the bytestring+attoparsec approach.

Well, I tried it... and it's still slower!

parsec2, String: (a little faster since last time since I have new computer) total time = 9.10 secs (455 ticks @ 20 ms) total alloc = 2,295,837,512 bytes (excludes profiling overheads)

attoparsec-text, Data.Text: total time = 14.72 secs (736 ticks @ 20 ms) total alloc = 2,797,672,844 bytes (excludes profiling overheads)

Sorry for asking but just for reference - what is performance of nanoparsec on your machine in this test? Regards
