Hi Scott

I've been playing a bit with PASE recently, and info-zip works well. I 
haven't benchmarked it against jar yet, but my intention is to migrate if 
it does work quicker. 

For those interested in trying it out, http://aixpdslib.seas.ucla.edu/ is 
one place to get AIX binaries from. I've managed to get clamav (free 
anti-virus tool) running in PASE but performance was actually slower than 
scanning the same IFS directory from an NFS mount on my Linux box. That 
may be just a config issue with PASE, as I haven't looked to see if 
performance can be tweaked.
