I haven't seen the effects you're describing and haven't heard any common cases of this - if V5R3 performed that badly overall, there'd be an outcry we'd all know about! Keep pushing IBM to help you fix it... somethings going on that's not 'normal'.. Hopefully you've got some before and after performance data that will help you prove your case...

I've had HORRIBLE performance since upgrading to V5R3. It's not one thing being slower, it's everything. V5R3 is a terrible performer, there's no question about it. Talking to various people, they told me: suggestion: The cache battery on your disks may be dead. reply: It's not. suggestion: You need more memory, the upgrade to V5R3 was the straw that broke the camels back. reply: I doubled the memory, and although it's faster than it was before, it's still much slower than V5R2 suggestion: You could X and Y and that'd make your applications more efficient. reply: True, but this didn't change when I upgraded to V5R3. They were like this on V5R2, and writing new, more optimized, code for every program on my system just so that the operating system doesn't seem so slow seems like a workaround rather than a solution. All of the "experts" I've talked to have told me that V5R3 performs just as well as V5R2. I checked into this before I upgraded. However, there's absolutely no question that this isn't true. I suspect that somewhere in all the changes of the virtualization engine, they did something that slows it all down. At this point, though, i'm stuck with it until we're able to budget for a faster computer.
