speed or compression
Obviously there is a trade off. For me I do want smaller files since I then have to ftp them -- and size does matter. But if it takes much longer to compress the file in the first place (the first step in pbs before FTPing the file), I may actually gain more time than I lose in transfer.
So I tried all three on an outlook.pst file (which is the one outlier to what I normally archive). it's a 65mb file.
The results:
zipx (strongest compression) 24 sec 7.3mb
7zip (strongest compression) 26 sec 6.7 mb
rar5 8 sec 9.2mb
