| no DON'T use psradm
use the console
see 3827.2 in this conference
see also mvblab::sable note 1835 and its reply .1
And in the manpage for psradm, note the following:
RESTRICTION
Do not use the psradm command to disable CPUs when benchmarking perfor-
mance, because the command does not provide an accurate reflection of the
performance of a system that actually has fewer CPUs. Accurate performance
results are obtained only when you disable the CPUs at the SRM console com-
mand level.

| 9355.3 | 2->1 cpu with psradm doesn't equal 1 cpu | SMURF::WOODWARD | | Thu Apr 03 1997 07:51 | 9 |
| To get "true" single processor performance, you just can't use psradm
to shutdown a cpu. Using the psradm command will not turn off SMP
locking when going down to 1 processor. Thus you will be paying the
SMP price on a system running only one processor. You need to shutdown
the system to the console, disable the proper processors, then reboot
the system.

| In addition to what John said in .2, the psradm command doesn't work in
V4.0B anyway (QAR 51839).
