Very suspicious slowness report - simple (native) stack trace initialization takes 5 seconds to finish.
There are also several complains about slow internal sampler in the log:
WARNING [org.netbeans.core.TimableEventQueue]: too much time in AWT thread org.netbeans.modules.sampler.InternalSampler@10067291

Reassigning.

No idea what was happening
Comment 4 Jaroslav Tulach 2013-11-20 09:33:39 UTC 
Suspicious sampling is more for Tomáš than me.
Comment 5 Tomas Hurka 2015-04-23 10:37:56 UTC 
Lat report is from 8.0 Beta. It looks like this issue cannot be reproduced in NB 8.0+. Closing.
