cpu competition strategy

• unix-time slice algorithm;
• windows- preemptive algorithm; according to priority, starvation time to calculate a total priority;

thread.sleep

• The operating system does not provide the recalculate the total priority of all threads interface, you need to re-compete the cpu through sleep, and the operating system will recalculate the priority before determining who uses the cpu.
• thread.sleep: tell the operating system how many milliseconds in the future not to compete for the CPU;
• Thread.Sleep(0): Do not participate in the CPU competition in the next 0 milliseconds = trigger the operating system to re-run the CPU competition immediately
• Thread.yield: is to give up the cpu
