The source for learning NetBeans.
Based on the New and Noteworthy page for NetBeans 7 Milestone 2, it looks like a new feature called ‘Profile Me Now’ will be added. This seems to be an attempt to improve the self diagnostic capabilities of the IDE itself…
I’v seen more than a few bug reports where someone complains about performance in their project, but cannot send the NB team their code due to proprietary rights issues, intellectual property, export control, etc.
With this feature users can activate the diagnostic tool, perform some action or actions, and then deactivate the diagnostic tool. This will generate a standard NetBeans Profiler snapshot which can then be submitted to the NB team for analysis.
