Hi all, We've now published new Generational ZGC Early Access builds (21-genzgc+5-33) on: https://jdk.java.net/genzgc Changes since previous EA builds: - Increased frequency of heuristic decisions - Tweaked heuristics for when to start a GC - Tweaked heuristic to distribute worker threads between young gen and old gen - Added diagnostic flags ZYoungGCThreads and ZOldGCThreads to set max number of young and old workers - Parallelized old generation remembered set remapping - Faster mark termination - Added needed instruction flushing to AArch64 Thanks, StefanK
