What's your favorite compression utility?

I ussually use bzip2, but compressing some db backups seemed to be taking to long (and stomping the box), so I did a quick test:

Started with a 512MB chunk of a MySQL table file

zip: 1:52, 288MB, system load around 80-90%
gzip: 1:40, 288MB, system load around 80-90%
bzip2: 5:01, 234MB, system load around 95-98%

Ouch.

Just switched the script over to gzip ... we'll see how it does.

FWIW, test machine is a 3.2GHz P4, 1GB RAM, 7200RPM IDE, Red Hat Enterprise 3.0
 
I've always heard great things about WinRAR, but it's interface sucks IMO. Oddly enough, in all my days of general computing, I've not much had the need for a zip program.

I just heard about 7-zip recently from a guy in our office. I'll have to take a look at it.

Generally bzip2, but it's too CPU intensive for some of my slower machines so on them I usually use gzip.

bzip2 is great for when you have lots of small files, but on big files your not going to gain a whole lot when you take into account the cpu stuff.

tar/split/gzip ownz ju 😛
