Same machine, o/s and all. Phil Katz' ZIP program uses a 386 is present, and he claims something like 40% too. I have seen a few numbers which would indicate that the NDP C is slightly faster than Xenix C, but I haven't retested with the newest version of Xenix C, which does produce better code (and has the ANSI extensions, too). -- bill davidsen (davidsen@crdos1.crd.GE.COM -or- uunet!crdgw1!crdos1!davidsen) "The world is filled with fools.
