Why on Earth would a Performance Testing application such as JMeter have such a low Java heap space by default.. i mean wouldnt it make sence to set this as high as possible for a Performance Testing tool ? 😞

    Their is a legit reason, you can spawn jmeter nodes on a distributed clusters of machines. But change the Xmx setting from default to increase the memory.

    Oh i see, yea i found that it is possible that way, just wondered why it was so low by default
    Cheers 😃

    I can think of a couple. First you don't want to eat up all of the available host memory to run some tests. Second, too much memory can be worse than not enough memory in jvm's.
