How can I have a clock resolution better than 10ms?



Starting with Solaris 2.6, this can be achieved with the following
entry in /etc/system:



set hires_tick = 1


This will set the system hz value to 1000.


In principle, you can also set "hz" directly, but that is not supported
nor recommended:



* Get 0.1 ms clock resolution/timer granularity
set hz = 10000


Solaris 8 introduces the cyclic subsystem; this allows for timers
of much better granularity without burdening the system with a high
interrupt rate. High resolution timers are available to root
only using timer_create(3rt) with a clock_id of CLOCK_HIGHRES.
