Optimization of performance issues for System.currentTimeMillis() in high concurrency scenarios

The call of System.currentTimeMillis() is much more time-consuming than the new normal object (the amount of time is higher than I have not tested, some say it is about 100 times)

System.currentTimeMillis() is slow because it has to deal with the system once

The background periodically updates the clock. When the JVM exits, the thread automatically reclaims
