One threadpool implements executor that adjust thread num based TPS
private Executor EXE=MyExecutor.getSingle(64,218,300000,30000,1.01,4,System.currentTimeMillis()-120000);
* @param LowThreadNum the min num
* @param highThreadNum the max num
* @param timeInterval check time interval,milliseconds.
* @param taskTPSInterval TPS time interval,like 20 secs
* @param changeRate the change rate we think TPS improvment
* @param threadStep how many thread num we ajust
* @param startTime when to start.
Situation which TPS will vary according to the environment and configuration scenarios.
Improving the utilization of CPU TPS improvment
