How to Improve Performance

The number of times that a user process spins and tests is specified by the
configuration parameter

SPINCNT

. The default value is 300. If you increase

the value of

SPINCNT

, you increase the period that the user process remains

in the

CPU

. If you decrease the value, you reduce the period.

You cannot directly affect the amount of time that the process spins between
tries.
