Build: NetBeans IDE Dev (Build 200907240201)
VM: Java HotSpot(TM) Server VM, 14.0-b16, Java(TM) SE Runtime Environment, 1.6.0_14-b08

User Comments:
kawazu428: re-opening the project group (55+ maven2 projects, "folder-of-projects" group) after restart, while into "task scanning"...  - I wonder whether the fact that all these projects are under SVN control might add (negatively) to that time...


Maximum slowness yet reported was 3579 ms, average is 3579

Comment 2 Jaroslav Tulach 2009-07-24 15:52:18 UTC

When opening this snapshot I get following exception. Assigning to profiler to be more robust:

Comment 3 J Bachorik 2010-10-08 12:25:13 UTC

Fixed the problem with reading the snapshot - http://hg.netbeans.org/profiler-main/rev/6aefeec94171 . You can carry on analyzing the root cause for slowness.

Comment 4 Quality Engineering 2010-10-09 15:26:27 UTC

Integrated into 'main-golden', will be available in build *201010090000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
