, unfortunately, so far, the performance of Java has been reduced from 32 to 64-bit.
Speaking of Java performance, two key aspects of runtime are: JIT and GC. JIT is used to execute code as quickly as possible. GC is used to extract as little time as possible from Code Execution (while managing storage. Therefore, the performance of Java is to allow JIT (with the help of more memory) to generate more ideal

Restart Mac.
The above is a permanent method. If only one 64-bit is used occasionally, press and hold the keys 6 and 4 at startup.
