distribution tape compression
Date: Thu, 15 Aug 1991 07:06 PDT
anyone know the relative tradeoffs of using compressed versus
non-compressed files when writing dist tapes?
On the negative side, the compression and decompression is obviously
comsuming extra time, but I have not noticed a significant slowdown in
writing tapes. (I have not done any actual time comparisons.) As far as
problems due to data loss, I have not experienced any to date.
It's possible that it's actually \faster/ to read a compressed file from tape,
since the bottleneck may be the tape speed and not the processor speed. I
think I've even noticed it being faster to read a compressed file from a UNIX
box across a TCP-FTP connection, though now that I'm using NFS the compressed
file (621K) seems to take twice as long to read as the normal file (1182K).
