Jemalloc 5.4.0 is on HN and the Rails advice is the same as ever. Most Puma memory bloat is glibc handing every thread its own arena. MALLOC_ARENA_MAX=2 recovers most of what jemalloc does, free. And since Rails 7.2 the default Dockerfile already LD_PRELOADs libjemalloc2. #RubyOnRails #PostgreSQL

Fifteen items are still open, and RC 1 and GA are both still TBD. If your workload found something in 19, file it before the freeze.
