I am surprised that you manage to have this working on that hardware. As you have replicas, it seems to me that you handle 2*12TB of index with 12*32GB of RAM? This is very close to our setup (22TB of index with 320GB of RAM (updated last week from 256GB) per machine), but we benefit hugely from having a static index. I assume the SSDs are local? How much memory do you use for heap on each machine? - Toke Eskildsen
