User Comments:
dbcurtis: I cannot tell what it is doing.  No real pattern.
I have been debugging (and it was really slow at some points in that).
But this last one was while editing and after typeing a "." after JFileChooser and waiting for the options to appear.



GUEST: On saving

Maximum slowness yet reported was 32846 ms, average is 28682

The on-save task waits for ~14 secs for javac parsing that runs on behalf of code completion to complete. I cannot see any particular reason why the parsing process takes so much time. Please investigate.
