[comp.unix.xenix] compress memory requirements

samperi@mancol.UUCP (Dominick Samperi) (02/07/88)

Roughly what are the memory requirements of compress? I recently applied
John Rupley's patches for compress 4.0 so that it works with Microport
SystemV/286, and it works fine with files that are no larger than about
250K, but it dumps core when I try to compress larger files. I suspect
that compressing larger files requires more memory than I have (a little
over a meg of available mem at boot time).

    Are you using 16-bit compress or 12 bit ?  This may not be totally
relavent but I received a patch that I applied to compress and it lets
me do full 16-bit compress/decompress on my Microport system. Its used
mainly with News feeds but I routinely compress files in the 1 MB size
region. Presently I compressed up my News2.11B sources and the "compressed"
file size is around 500K. Me and a freind also swap a lot of DOS software
via UUCP and have compressed files with a size of 1.2MB. If your interested,
I can send you the 16-bit compress patch. Im currently running with
3MB of main memory with 1960K available after boot.
