Message-ID: <7273.25e41a7a@dit.ie> Date: 22 Feb 90 16:59:37 GMT References: <36517@iuvax.cs.indiana.edu> Organization: Dublin Institute of Technology Lines: 77 I downloaded the PAX program yesterday from cbip. I had requested it from SIMTEL only about 2 weeks ago, so I decided to make a comparison. SIMTELs file was ARCed. The cbip file was ZOOed. I ZIPped the files for comparison. I didn't do a time comparison, but these figures indicate a ~25% saving in file size, and if cbip ever gets real busy again, that figure has to be significant! Given that it's PC only code, the UNIX compatibility issue must be weighed against this bandwidth saving.
