if you go to your applications installed directory the go to etc folder then open the applicationName.conf file and change the min and max heapsize then save and restart your application, that should change your applications heap size, check the change in your application ide log, thanks

Go to your project's properties (right-click on left hand side of the Netbeans interface), and change the VM options field to this:

The 64 is the minimum VM size (in MB) and the 2048 is the maximum VM size in MB.

It looks like from version 6.0+, netbeans auto-defines -Xmx value to be 1/3rd of available memory, as specified in official wiki here:

http://wiki.netbeans.org/FaqSettingHeapSize

Status bar should show used memory. Do you find it locked far less than what you could expect, say 33% of max?

I faced the same problem as yours. Change the memory setting on that config file: C:\Program Files\NetBeans 8.0\harness\etc\app.conf
