[Al Barsa <barsa@xxxxxxxxxxxxxxxxxxx>]

With no disrespect, I don't think that a model 400 is supposed to support
V5R2.

What hardware do you have?

I saw a significant decrease in performance after moving from v5r1 to v5r2
on a model 400 at my last position.

IBM determine that basically I was SOL as the OS had been optimized for the
newer hardware.  Luckily, the move to v5r2 was just in preparation for the
install of a new 270.
