snapshot data

Hello. Since some days ago, NetBeans 8.1 started to do some really intensive task on the CPU, ranging from 70 to 90%. Unfortunately I still don't have steps to reproduce the issue, since it happens apparently randomly. I'm attaching the profiler report.

Thanks

it looks like all I/O operations are slow. There is a lot GIT related code in the nps snapshot. Can you please capture snapshot once more (http://wiki.netbeans.org/FaqProfileMeNow) and
1) attach npss file (not nps) - you can attach it directly to this bug from selfsampler tab
2) attach messages.log file at the time you captured the profiler snapshot.

Thanks.

Hello, I'm having the same problem, suddenly (when not even working on the IDE) netbeans starts to use a lot of CPU. I attach the npss file and the messages.log file.
