I have lots of configuration and extentions, and though I've written it as cleverly as possible, I must admit that the interactive feel of 'emacs -Q' is faster, not much but I sense it. Just as I sense the one-core solution is faster. Try bring in a bunch of stuff in .emacs if you didn't already - w3m, LaTeX, Gnus, everything you can think of - and then compare that to 'emacs -Q'. If you don't feel a difference, perhaps you already hit the roof. As for your CPU I don't know what optimization, parallelizations, and so on are at play at that level. It is more like a electrical engineering thing anyway :) But do enlighten us if you know. -- underground experts united
