MCreator recommendations

Hello, when using MCreator, it often gets stuck when opening projects. This is a problem caused by Java JVM. Although MCreator uses openjdk9 to run MCreator, it still gets stuck. I try to improve the process priority of Java, but the effect is still not ideal. Do you have any configuration files for configuring JVM? I want to configure it separately to improve efficiency. Or hope to improve the Java code in the next version, hope to refer to my suggestions, thank you!
