Using C would also eliminate the need for all those passes. It's faster to do multiple passes in Perl since each pass isthree of the passes are entirely in C.

Here's a trick that's been known to speed things up if most of your data is ASCII: Read four bytes at a time. If none of them have the high bit set, you've just handled 4 chars at once.

The extra work would probably slow Perl down, but it probably speeds up a C solution. Be wary of alignments.
