fast implementation of the unix utility wc?

Hello,

	I wonder whether s.b. has a fast
implementation of the linux utility
wc (word count) to share?
All it does is it counts how often every word
in a text appears and at the end it sorts
that list and gives it out.

I'm especially curious what tricks people suggest
to speed-up the IO.

Thanks a lot for your help,
 
Armin.
