It does not use mmap right now. And this causes a significant perforamce hit on larger files. An older version (I'm thinking .4) would give equivalent performance on smaller files, <75k or so, occassionally faster. However, larger files really drag it down, often slower by 900%. > I haven't tried it out yet because I haven't seen it hit 1.0 :) The > only good pre-1.0 software I've seen has been the GIMP, XRacer, and > some little utilities (like a program called stat(1)). > > That reminds me.

Worth it is here defined as > "would be accepted to go in usr.bin." I once saw a version of stat that carried a public domain statement on an HP-UX software archive, I'll see if I can dig that up for you.
