Scheduler processor time slice

The processor time slice is the amount of time a SCHED_RR thread can absorb before the scheduler switches to another thread at the same priority.

You can use the timeslice option of the schedo command to increase the number of clock ticks in the time slice by 10 millisecond increments (see Scheduler time slice modification with the schedo command).
Note: The time slice is not a guaranteed amount of processor time. It is the longest time that a thread can be in control before it faces the possibility of being replaced by another thread. There are many ways in which a thread can lose control of the processor before it has had control for a full time slice.
