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.
