Thanks to Cory Erikson for his response, however it was HP Gold support that
provided me with the answer. If the system is experiencing high idle/wait
times on CPU then changing this parameter is a way to improve performance.
Right now I am not seeing any degredation in performances so I will leave
the round_robin_switch_rate alone for now.

Subject: round_robin_switch_rate
Admins,
I have a GS160 running Tru64 5.1 pk 5 and I was checking parameters
yesterday and found that my proc: round_robin_switch_rate = 26. It is my
understanding that the Time_Quantum = hz / round_robin_switch_rate which
would give each process 38.46 milliseconds of processor time. After asking
my collegues none could remember changing the round_robin_switch_rate from 0
to 26. Could anyone give me any pointers as to possible cenarios where
changing this parameter from 0 would be to an advantage? Is this parameters
value dependent on other parameters being set? I will summarize.
TIA,
Chris Bryant
