    Subject: Does a larger gc-cons-threshold mean a faster Emacs?

Up to a point, yes.

    (setq gc-cons-threshold (* 8192 8192))

    Which seems to yield decent speed (though Emacs uses 50M)

    If I set it to anything higher... I get CONSTANT gc and lock my CPU at 100%
    (emacs is dead)

Precisely what larger value did you use?  Was it so large
that it caused arithmetic overflow and gave you a negative number?


If you used a sufficiently large value, it would overflow.
