In my opinion, the best GC is a stopped GC.
So, we can just halt lua's GC for a while, then restart it when system load is low.

Okay, okay, I'll resist the temptation to poke some more... :-)

But, have you seen a Comp Sci paper that implements your idea? I don't believe I have. Would be interested if any such paper can be found.

                using such an allocator implies the need for a moving
                GC. The
                current Lua GC is non-moving. Revising this fundamental
                choice is very complicated while keeping the current
                Lua/C API.

            I think that a moving GC is bad for CPU which has a
            multi-cache modern
            architecture .

            One single factor will hardly decide if a moving GC or a
        mark-and-sweep one is better. Point in case, the generational GC
        allocates memory faster.

    To put it in another way... Data needed, otherwise it's
    hand-waving!!! :-) ;-)
