I usually give it 2gb but you could probably give it 3gb or even more if all that's running is Jmeter.
No matter how much you give it, it's never enough. The biggest offender in memory consumption is the "view results tree" listener. If you disable that in0 high-memory tests, you'll probably find that you have no more memory problems. If you're doing a huge image or something with jmeter, the view results tree listener will hold on to the image for the entire test. If you're downloading several large images or the same one multiple times, you will quickly run out of memory. My one test that does something like that uses two listeners that write successful and failed requests to disk. I can just fire it up and if I see any failed requests then I know my test failed. -- Bruce Ide [email protected]
