Far and away the slowest part of computing is the user/system interaction bottleneck. One free technique that will give a roughly 10% productivity speed up is to convert to a Dvorak keyboarld layout instead of the old and slow Sholes layout (Qwerty). I did this three years ago and it pays off over time. For developers, the only real metric is maximization of overall productivity over time. This is why those programmers who've switched from MS Windows to MacOS or to Linux/XWindows rarely switch back.
