New Screencast link (previous got deleted accidentally): http://screencast.com/t/0fDMotUe58l1 Note: sound is muted intentionally. Can you please profile the ide? (There is action Profile IDE which can profile the running IDE and attach the captured snapshot to the selected issue) Can you please provide ide, it can find where can be problem with performance. I am new and I am trying to find the profiling process you suggest me doing. Unfortunately, NetBeans' guide doesn't helps a lot: https://netbeans.org/kb/docs/java/profiler-intro.html 1) There is no Java sample folder in New Project's wizard, nor installing the Java Development Kit enables such a thing. 2) Using keywords in the `help` bar, nothing can be found. "Profile", "profiler", "calibration", "monitor" keywords do not reproduce any results. Additionally, I cannot find anything like: - Advanced Commands > Run Profiler Calibration from the Profile menu or - Choose Profile > Profile Main Project from the main menu Can you please describe the process of profiling IDE having in your mind you speak to a beginner? http://wiki.netbeans.org/FaqProfileMeNow this is good tutorial how to profile netbeans and report performance issue.

Salfsampler showing performance issues during examining a minified file
Contains about a minute of profiling the IDE.
Created attachment 145582 [details]
Small selfsampler file
Contains few seconds of profiling, and a cumulative stack depth indicating "3,091".
I am sorry, this looks to similar issue as in #237724 ... I see that you don't have Retina, but in both samples I see that AWT-Thread is slow down by sun.java2d.opengl.OGLRenderQueue$QueueFlusher.flushNow() 52.954372 59,393 ms (53%) 11.0 ms This is JDK Problem. Eclipse has its own GUI implementation, so they don't use java2d libraries. I cannot fix this in Netbeans Editor. JDK Problem. Already discussed in Bug #237724 This topic should be set at a higher or same priority class with the "already discussed" topic which is P2 not P3, same as the reported bug at Oracle: http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8029253 whoever has this problem too, vote there. |
