How to know the number of worker threads used by the GWT compiler? very simple check out the "Task Manager" of your computer (CTRL+ALT+DEL and choose option 'Show Task Manager'), and see how many "CPU Usage History graphs" do you have (as I said before, I have 4).
In my case, the improvement was about 3x times, from the ~180sec to about ~60sec. Not bad, ehh?
