Sometimes you feel your favorite IDE is slower or the memory consumption is higher than you expect, so you usually file a bug. But just a description is not enough to solve it. For this kind of issue, the developers need more information as steps to reproduce and, of course, the heap and/or thread dumps of your system. Based on this information bottlenecks can be identified and a solution implemented.
But getting this information is not trivial for many users and NetBeans IDE has since version 6.7 a feature named Profile Me! which helps to make this task easier:
In this page you can see step by step how to get the thread dump from your system, in the section "Profile Me Now!" and just below that you can see the section "Snapshot me!" with details about how to get and send the memory dump. Many people are not aware of these features so I hope this post helps you to file better issues to the NetBeans project, helping to make this the only IDE you need.
