A DESCRIPTION OF THE PROBLEM :
When I compile java files using javac command of jdk21 and jdk11, the speed is significantly lower than jdk8.jdk8 can always execute results quickly, jdk11 and jdk21 are 7 times slower than jdk8.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
time ./hotspot-jdk8u352/build/linux-x86_64-normal-server-fastdebug/jdk/bin/javac Test.java
