Hi, I have been running with ZGC for quite some time and find it to be the superior choice for my purposes. With low to moderate load on the broker G1GC will be slightly faster in terms of overall messages in+out of the broker. However, system response times and latency is far better and more consistent using ZGC, especially when working with lots of destinations and clients under high load. I would suggest using the bundled "perf" tool and trying this out for yourself though, as with everything YMMV.
I have not experienced any "behavioral" changes in the broker with different GCs though and I really would not expect that to happen either. I'd guess that has to do with something else.
