“Voluntary Yields” reports the number of times a task completed or yielded after running for the configured amount of time. The Adaptive Server engine switches context from the task that yielded to another task.
The configuration parameter time slice sets the amount of time that a process can run. A CPU-intensive task that does not switch out due to other causes yields the CPU at certain “yield points” in the code, in order to allow other processes a turn on the CPU.
See “Scheduling client task processing time” for more information.
A high number of voluntary yields indicates that there is little contention.
