Well, I suppose that's part of the problem. What does O3 improve? Does it decrease the CPU-load of stuff like mplayer? Does it improve the response speed of window managers and typical office and internet applications? Or does ist just help when it comes to pure ALU and FPU power, for example bzip2, gcc or spamassassin?
