I want to see a source on this. Golang's GC is often touted as better than Java's but every real world benchmark I've seen shows that it sacrifices a lot of throughput for low pause times, essentially by running much more often.

Java's new garbage collectors, ZGC and Shenandoah, have average pause times of 0.3 milliseconds on heaps less than 4GB. I find it unlikely that another language has pause times shorter than that given the sheer amount of work put into Java GC over the years
