You need to get the latest DB2 Group PTF's. This should fix it.

We are running lots and lots of queries on our systems.
Recently we have upgrade to V4R5M0 and now we experience very very long
runtimes of the queries.

You can see that when the query runs, it is reading 300 records at the time

on a model 730 with 2GB main storage.
When I run the query on another system it is reading by blocks of 15000.
The other system is a base model 620.

This problem is happening on lots of systems, but I tested the query on a
model 820 and did not have any problems.

Another branch of us also runs on a model 620 and there the problem is
occuring. PTF level is the same and IBM cannot find the solution.
Does this ring a bell to anyone?

Maarten
