It took about ~12 hours to fill up all the heap, and then it never goes down. constructor. In short, the actual maximum utilized memory by your application is a function (credit to the link above): Max memory = [-Xmx] + [-XX:MaxPermSize] + number_of_threads * [-Xss] Of course the JVM. Shared libraries get in the way of a bigger heap. This will give indeed better results in your case, since using Jmeter, you are stressing the server that will need to increase the heap. Setting Xms and Xmx for standalone Java applications: To set the Xms and Xmx parameters for a standalone Java application, you can specify them as command-line arguments when starting the JVM.

On a Unix/Linux system, you can do. img count=1 bs=1 seek=$ ( (10 * 1024 * 1024 * 1024 - 1)) This is very fast because only one byte is really written to the physical disc. But the JVM typically starts with a smaller heap, and expands it as required. Does it mean OS can use up to (15-4)=11 GB out of which meta space memory will be allocated? Maybe: There will be other process on a Windows machine. The -Xms and -Xmx options are used to set the initial and maximum heap sizes, respectively, for the Java Virtual Machine (JVM).
