Problem method is Utilities.actionsForPath().
It blocks EDT for a while.
Reassign to evaluation.

Well, try to fix your harddisk, so loading of classes from it is faster. 

Should you consider this case important from CND point of view, try to pre-load important objects into memory when a CND project is created/opened. When the actual right-click on the Makefile data object happens there does not seem anything to do to speed things up (in case of such a slow disk access).

Looks like the problem is not only with disk, but with system (and jvm) in principle. The other strange hotspot method in snapshot is SwingUtilities.isEDT which goes into "native" and spends 10sec there (while being in EDT)

Problem in software/hardware of user computer.
Do not fix.
