NAME
NSTRSCHED - number of STREAMS scheduler daemons to run
VALUES
Failsafe
Default
Allowed values
Recommended values
DESCRIPTION
This tunable defines the number of multiprocessor (MP) STREAMS scheduler daemons to run on systems containing more than one processor.
Note that uniprocessor (UP) systems do not use an MP scheduler daemon, but both MP and UP systems always have one UP STREAMS scheduler
(supsched).
If the tunable value is set to zero, the system determines how many daemons to run, based on the number of processors in the system. If
the tunable value is set to a positive, non-zero value, that is the number of smpsched daemons that will be created on an MP system.
Note: This tunable is for use by specific HP products only. It may be removed in future HP-UX releases.
