i never measured it to see if it is 50-60 times slower, but yes, gzip blows
bzip2 out of the water on speed. I wanted to use bzip2 to compress multi-GB
weblog files, but gzip beat it my miles, and bzip2 wasn't THAT much better @
compressing it to make it worth it.
The box I had tested this one was a Dual Opteron 250, 4 GB RAM, SATA drives
gmirrored, FreeBSD 6.1 (or 2), amd64.
