It has some impact on overall execution time (throughput), mostly through being able to bump allocate. The benchmark I used in the article shows a large gain, though the real-world effect is much less.

But GGC is mostly about reducing pause times (latency). (And yes, people have taken to calling that "jank". I still resist the term when I can, since it's no more precise than anything that came before but people seem to think it must mean something specific.)
