Dave, you are probably correct in being cautious about making
a sweeping change without looking for evidence first. For more
details on the PAV support that went out with the APAR you
referenced, see http://www.vm.ibm.com/perf/reports/zvm/html/520pav.html.

Well, I know that VSE can't do PAV, but z/VM 5.2 w/ APAR VM63952 can do
it for VSE, providing that the volumes are minidisks. I just don't
think that it is going to get me much (if anything) with a single
guest.
Would VM minidisk caching help throughput in a large batch environment?

Dave, you may want to cross-post this one on VSE-L..could generate some good

If you made the DASD mini-disks instead of DEDICATED you can try VM mini disk
caching.
I am pretty sure PAV is z/OS only...
All the regular tuning things can reviewed also
- VSAM buffer tuning -
- Sequential file blocking
- Application s/w tuning
- VSE or VM paging?

Did you format the entire paging space? It needs to be pre-defined with 4k
