Ah, ok. In recent times, I've tried to reduce our memory
usage. Do you have any nunbers that this has grown again? It
would be a nice little project to compare, say, 2.2 and 3.0
with master for some typical workload in terms of RAM usage.
That should either give us hints how bad we suck these days
or give NAS vendors arguments to switch to latest code.
