I don't know other languages/VMs that requires to set JVM's Xmx/Xms equivalent parameter. Why only JVM requires it? What about to just set unlimited by default?

- winrid 6y agoGenerally, you want to leave some memory available to other things, like the OS, buffers in the network stack, etc. Having a limit for the VM is helpful. Also, by default it is automatically 20% of available memory. Personally, I've had to tune this kind of stuff with every VM I worked with (JVM, Node, PHP). :)
