Usually the load times of that version are no where near as bad as you described. "10 seconds form pressing right click for the menu to show up"? If you meant that literally, something is seriously wrong with your setup. Should take around 0.5 - 1.0 seconds for the menu to pop up. By comparison, on the present developer version, it's virtually instantaneous.
Btw, that v1.0.0 version from a year ago is still termed and considered "beta".
