Leif, how are you measuring your time?  Are you including the database I/O?
My screen requires about 20 database reads to build it.  So let's compare
apples to apples.  If you're doing 20 DB reads and formatting a screen in
1.35msec, you're doing quite well.  Then again, I would ask how you measured
it, and let me repeat your results.

I got MY results by doing a WRKSYSACT, recording the elapsed CPU of the job,
paging up and down 200 times, and rerecording the elapsed CPU.  How did you
measure your time?

There are lies, damn lies and statistics.

Joe
