Hello,
I'm looking for some suggestions on how to possibly improve I/O
performance to a PDS. A user is running a job that is reading a large
parmlib (through PROJCL I believe). I think the access is random
rather than sequential. The parmlib has ~180,000 members is has an
LRECL of 80/BLKSIZE of 27,920. The performance team has reviewed a
found ~ 6ms response time to the volume that houses the PDS with most
of the time being connect time.
Thanks,
Chuck
