I think I originally wrote those parsers *before* ByteString existed. (But then added ByteString support when it was available). Now we have attoparsec, enumerators, pipes, smallstring, and all sorts of new toys :) So, I will say that the Debian library has acceptable performance for at least one application (the autobuilder) which regularly reads in entire Packages and Sources files as well as other debian control files. And, patches to make it even better would be acceptable :p - jeremy
