Today, it took 20s, see  id #551151.
I took a dump during and after this slowness.

Comment 7 Miloslav Metelka 2012-06-07 08:28:36 UTC

Partially solved by 194965 (MainMenuAction.setMenu() getting info from MimeLookup is now rescheduled from AWT).
Also AlwaysEnabledAction$CheckBox.isPreferencesSelected() leads to calling EditorActionUtilities.getGlobalPreferences() which is slow since it reads from MimeLookup. I have added the call into editor's warmup.
