Timeslice recommendations

I have been tuning a 730 system that someone had sorely messed up. They had 
QINTER class with a time slice of 4000 milliseconds and had left QBATCH at 5000 
milliseconds. They affectionately call CFINT001 and CFINT002 'dumb and dumber' 
for obvious reasons, as they were continiously kicking in. They classes are 
running at 200 and 1000 respectively and the paging faults look much better and 
CFINTXXXs are less of a distraction.

Continuing on the same tack, there are other classes that seem to have defaults 
that seem to be way high for todays Risc machines.

Here is a list of those classes and timeslices:

Class                   Timeslice
QPWFSERVER              3000
QP0LBIOD                2000
QP0LLCKD                2000
QP0LMNTD                2000
QP0LNFSD                2000
QP0LRPCD                2000
QP0LSTATD               2000
QSPCICLS                1000
QSYSCLS                 2000
QSYSCLS07               2000
QSYSCLS10               2000
QSYSCLS20               2000
QSYSCLS25               2000
QSYSCLS35               2000
QSYSCLS50               2000

Obviously they aren't as big as hitters as QINTER and QBATCH. Has anyone played 
with these classes and have any recommendations?

Thanks,

Jay

p.s. IBM looked at there performace data and said 'it was running within design 
limits' and did not make any recommendations. ahhhhhhh
