A DESCRIPTION OF THE PROBLEM :
Are there significant performance differences between different JDKs when handling large amounts of calculations?
When I execute this code using jdk-21.0.2 version, its time is 11.726s. When I use "-server" the time drops to 4.897 seconds. Does this process result in optimizations that should be performed but are not?
in addition,
When I execute this code using jdk-11.0.15, the time is 24.591s, and when using "-server" the time is still 23.912s
When I execute the code directly using version 11.0.22, the time to execute the code is 1.883s.
When I use the 8u352 version, the time taken is 2.509s.
  So I would like to ask, is it the difference in processing performed during optimization that causes such a performance difference?Are there significant performance differences between different JDKs when handling large amounts of calculations?
