I don't have the exact numbers any more, but tests I ran under MS-DOS
when ZIP-1.9/UNZIP-5.0 where first released showed about a 10%
improvement of PKZIP 1.1 and a 5 to 10% improvement over LHA and ARJ.
All test done with the default compression method. Time wise only
PKZIP was faster.
Previous postings have repeately said ZIP does not handle permissions.
This is not true. When I use zip-1.9 to compress files in one directory
and then expanded them somewhere else, they are restored with the original
permissions.
