Hello Charles,
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.

Hello,
We installed V5R3 a couple of weeks ago. Since then one ofour nightlycritical path jobs has more than doubled in run time.
I know I'm joining this discussion late (I haven't been able to keep up with e-mail this week) but I just wanted to say that I've been having similar experiences with V5R3.
Since upgrading from V5R2 to V5R3, pretty much everything on the system is slower. I don't mean just SQL or just database -- pretty much everything is slower.
I suspect that my problem is lack of memory -- that V5R2 used less memory than V5R3 and that the difference happened to matter on my machine, since I haven't heard anyone else opine that V5R3 is slower.
Unfortunately, I've been too busy to find that out for sure. If you come up with a good solution to your speed problems, please post them here. I'd be interested to see what you learn...
