Thanks for this info! Doing a quick googling on elasticsearch and ZGC I just found this https://github.com/elastic/elasticsearch/issues/44321 https://github.com/elastic/elasticsearch/issues/44321 where the official response from elastic is that only G1GC and CMS are tested and supported. I still think that it will be worth trying Shenandoah or ZGC if/when we ever get down to do some experiments with larger heaps.

Last time I ran with ZGC the main problem was that ES OOM circuit-breakers are going nuts since they are not prepared to have memory mmaped 3 times. So their calculations are off by a factor of 3 blocking most of requests for no good reason. Running with oom circuit-breakers disabled is something I’m currently considering.
