How to speed up Java VM (JVM) startup time?

Question

I am running tests that start multiple JVM processes. Summary startup time of JVMs is quite significant compared to time of actual tests that run inside JVM. How do I speed

Answer 1

To add to what has been said by others, next version of Java (Java 7 Java 8 Java 9) should add a new improvement in JVM start-up times, due to modularization of the platform, according to this link.

One benefit of modularization is that the platform is a smaller download, potentially improving start-up performance. Having a smaller memory footprint also enables significant performance improvements, especially for desktop applications.
