Jeez, Jerry. Great minds think alike.

Booth,

First, the list is apparently being cached so that subsequent executions
don't have as much to consider. Sort of like doing a scan on a source PF in
PDM; the first time is relatively slow, but the 2-n scans scream.

Second, is that for a relatively recent period (1-3 days)? I'm with Rob
and others on this. Since V5R4 I've always used the EXPDATE/DAYS options on
printer files; usually no more than 3 days (to cover weekends). And then
set up a job in the scheduler to run the DLTEXPSPLF command shortly before
midnight every day.

Narrowed down further. Here is the command:

WRKOUTQ OUTQ(QUSRSYS/PRT01) OUTPUT(*PRINT)

10,000 spoolfiles are in this queue.

Run from the command line = 2+ minutes.
Run again immediately, = 3 seconds
Run again 5 minutes later = 3 seconds

Well, that's a generalization, but it seems to me that Booth needs to
narrow it down even further. I have trouble seeing a 4-minute
initialization subsequently dropping to 6 seconds, except in a case where a
job is having trouble allocating a particular resource the first time.
