If you are collecting type 19 records, then SMF has to gather the data for them from online DASD volumes at every switch. If you happen to run into volumes with SYSVTOC enqueues, it can take a LONG, LONG time. 30 minutes is not uncommon for us.

I was wondering on a quiet system, if I issue an I SMF command, about how long till the switch? I am seeing about 1.5 mins from command to switch.
