Comment 3 Vladimir Kvashin 2012-12-07 08:21:27 UTC 
First snapshot shows the following:
Half is spent here:
APTAbstractWalker.includeImpl -  48%:
    APTAbstractWalker.serialIncludeImpl - self time: 23%
    APTAbstractWalker.serialIncludeImpl - very deep #include recursion - 24%
Another half time is spent in gatherinh macros, which in turn lead to the above mentioned methods again.

As to the 2-nd shortcut, I don't see it is relevant at all - I don't see completion there at all. AWT is OK.
