This leads me to wonder what the effect of the new GC will be on a
single-processor machine. Will Emacs run slower on those with
thw new GC?
That question is sort of ill-posed. From Gerd's description, MPS is both incremental and multi-threaded/concurrent. I don't know if the dedicated thread can be disabled, but even without it one would expect to get lower pause times from incremental collection, possibly at the cost of higher total collection times.
