1. In the video they say that in practice they see average pauses of 1ms and max pauses of 4ms.

2. It's still very early days for ZGC, but there are more established low-latency Java GCs. A non-realtime one is C4[1] (used in the Zing JVM), which then added generational collection to a design that is similar to ZGC. They report[2] a few 0.5-1ms pauses per hour

Thanks for the links.

This is definitely great engineering.

I also recommend this short presentation of ZGC: https://dinfuehr.github.io/blog/a-first-look-into-zgc/
