How exactly is the Java stack set up?
For university, I shall determine what the biggest possible Fibonacci number that is calculated by a recursive method and can be handled by the stack.
The interesting thing is: Tests showed that it doesn’t matter how much -Xmx and -Xms the JVM has. I am able to run up to Fib(4438). But the results aren’t consistent. Somtimes it goes down to 4436.
Is there formular for the stack?
Any increase of the stack via -Xss 4096m doesn’t make a difference.
-Xmx and -Xms sets memory accessible for JVM heap, you need to increase stack size, you do this with the help of -Xss option.
