Have you had experience configuring or using the -Xms parameter when launching JVM?

The -Xms parameter in JVM sets the initial heap size allocated when starting a Java application. Using this parameter helps control memory consumption and can improve performance, especially if the application requires a large amount of memory from the start.

For example, if you know your application will use at least 512 MB of memory, you can set:

java -Xms512m -jar myapp.jar

This allows the JVM to allocate 512 MB immediately, avoiding costs associated with dynamic heap expansion during runtime. In my experience, I configured -Xms for server applications to minimize garbage collection pauses and ensure stable operation under load.
