Mark and I have discussed this in the zip digest, suffice it to say that my measurements of the UNIX versions of public zip and lharc 1.00 as posted by me to the alt.sources group a few months ago is that lharc is faster by about 2:1 for text and 5:1 for (compressible) binary, while giving very slightly smaller files. After the new string matcher is in we will probably agree on a set of test files and machines and run the tests again. My tests are almost all done on either Xenix or Sun4. I doubt that this means either of us are wrong, but we are getting different results and your results may vary. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
