Gzip is much better than compress. Fast, compressing much better and more reliable for uncompress. Couple of years back I produced comparative results on this list. Only observation is high CPU usage for gzip than compress though. Regards Rafiq From: joe_dba@xxxxxxxxxxxxx: oracle-l@xxxxxxxxxxxxxxxxxxxx: gzip vs. compressDate: Tue, 22 Jan 2008 13:54:15 -0600 Which is better to use gzip or compress? All of my work is done on AIX 5L 64bit server. I am doing cold backups of databases where I tar and then compress the resulting file. I have always used compress, but I read that gzip gives better compression. Any thoughts will be appreciated. Shed those extra pounds with MSN and The Biggest Loser!
