Tweak JVM parameters

I have a java program that demands too much processing power. I know my hardware CAN support much more than that. But the JVM is alloted only limited resources. I want to know whether we can allot more resources to JVM? Let's say I want to use my PC only for running the java program and nothing else so that my JVM can utilise the full power of the PC. Please give some hints.

You can give processes more priority, but sometimes only when the process is already running.

On Unix, the "nice" command can be used for this. On Windows, you can change it using the Task Manager: go to the Processes tab, right click the process, use Set Priority.

On all systems one warning: don't give the process a too priority, or it will make your system unresponsive to anything else if the process is using all resources.
