RE: Loading TR9 on V7R1 - Performance Issues!

That's why what happened is so strange. Setting the PTF as *DLYALL shouldn't have changed anything at all on the system. But having what happened so soon after applying these PTF's delayed seems more than just chance.

I didn't use the "Immediate" option. I set all to delay until the next IPL.
