Re: Zip Compression

DTACPR(*MEDIUM) strikes a good balance between speed and compression. I ran some benchmarks on it some time ago and the compression is almost as good as running DTACPR(*HIGH), but it executes much faster.

I've found that using the *HIGH compression available with the DTACPR parameter with V5R4 is quite impressive. The amount of space saved by ftping that to a PC and then running winzip on that was negligible. Not like DTACPR(*yes), that didn't get near the compression. 

But methinks you are right with PKZIP.  See also tar in qshell.
