Re: SQL Performance in V5R2

[rob@xxxxxxxxx]

Without a doubt ensure that you order the latest cume, hiper group and 
database group.  If you've had the V5R2 cd's laying around for longer than 
4 or 5 months, then throw away the cume CD's that came with it and order a 
new set.

One of the things listed in "What's new in V5R2" is a rewrite of the query
optimizer to improve SQL / query performance. We are upgrading soon, but
being asked now about things we can do to aid in CPU usage and user
experience. For those of you that have already gone to V5R2, has there 
been
a noticeable performance improvement? Our apps are VERY SQL intensive to
accommodate completely dynamic sorting and filtering, and while our system
performance is good (box and index tuning done and reviewed regularly) we
are always prodded by our hardware guys to see if we can't get a few more
RPMs out of the hamster wheel.

Any shared experience would certainly be appreciated.
