[comp.sys.sun] Tuning parameters for performance

mks@cbnewsm.ATT.COM (manishkumar.sharma) (03/08/90)

I am running a benchmark on the Sparc 4/490 that simulates several user
processes.

1. What parameters can I tune to get the best performance?  The benchmark
is both cpu and disk intensive and I need to use both efficiently.

2. Is there any way I can get Wait for i/o (wio) time?  Vmstat, iostat and
pstat are not as helpful/comprehensive like "sar" is in sysV for system
activity numbers.
