I recently upgraded from a 310 to a 620-2180 with release 4.1  ..  512
meg memory, 62 gig internal 8 gig dasd Raid 5.  I also installed a
620-2175 for hi availability using mimix. I am having a problem when
jobs are initiated. Takes 4-9 seconds when a menu option is selected -
but sub second after job is running. Especially bad if user hasnt hit
enter key for a while. Preopening files did not help.. Did not have this
problem on 310.. IBM has thrown it back into my  business partners lap
saying it is either a configuration problem or needs performance tuning.
I did split up some pools as per IBMs recommendations but it has had no
affect. I went from a relative performance of 56.5 on 310 to a 113.8 on
2180, and overall performance is worse. Am I wrong to think the 2180
performance should be screaming (louder then my boss !!) ? I even moved
my programming staff to my backup 2175 , still no difference.. IBM seems
to be passing the buck, and I am stuck .Any input ??  thanks
