> That's 999,000 packets every second, or 33k pps across your whole cluster. For reference, GigE line rate with full 1500 mtu packets is 80k pps. If you actually have 1000 nodes worth of work, the heartbeats are not at all a big deal.
Using up almost half of your pps every 30 seconds for cluster maintenance certainly seems like it's more than "not a big deal", no?
