why does my Java console program take up so much CPU time
To determine how much memory you can spare for Java, try this: stop your Java process; run free -m; subtract the 'used' value from the "-/+ cache" row from the total memory allocated to your server and then subtract another 'just in case' margin of about 10% of your total server memory. The number you come up with is a rough indicator of the largest -Xmx setting you can use on your server.... Java runtime uses it to allocate memory to objects and Java Runtime Environment (JRE) classes. When an object is created, it is always created in Heap and has global access. That means all objects can be referenced from anywhere in the application.

  • To gauge and measure the actual memory usage of your program, you can use the memory_profiler module. I played with it a little bit and I’m not sure I trust the results. Using it is very simple. You decorate a function (could be the main(0 function) with @profiler decorator, and when the program exits, the memory profiler prints to standard output a handy report that shows the total and
