The second 7.4beta report
http://statistics.netbeans.org/exceptions/exception.do?id=683167
is more about

   org.openide.awt.MenuBar$LazyMenu$MenuFolder.createInstance(): 3725 / 0
        org.openide.awt.DynaMenuModel.loadSubmenu(): 3725 / 0

many UI components are created in one AWTRun "pulse". Each of them having at least one access to a resource (name, image). Splitting that initialization to multiple "pulses" would improve the responsiveness.
Comment 3 Jan Peska 2014-07-14 12:22:22 UTC 
Only report from 8.0 is cause by slowness in org.netbeans.modules.form.GandalfPersistenceManager.loadComponent -> reassigning to the guibuilder for evaluation.
