Most of the slownesses are caused by slow NbBundle.getMessage().

Report http://statistics.netbeans.org/exceptions/exception.do?id=682807 is a JDK bug where JFileChooser actions are blocked by background sun.awt.shell.Win32ShellFolder2 operation. It has already been reported to JDK team.

http://statistics.netbeans.org/exceptions/exception.do?id=679498 is the NbBundle.getBundle slowness. As far as I can say, the .properties files (and other resources) are properly cached in the JARs - At least org.netbeans.Archive.getData seems to serve all requested resources from its cache on 2nd run.

However, the cache gets turned off when main windows is shown. Any functionality loaded since them will require opening JARs and this may be slow, especially slow when other IOs are running on background. I don't believe there is a way to prevent this right now. Closing.
