> RAM amount might matter too. 12GB vs 32GB is a bit of a difference.

Allow me to bitch hypothetically...

We, and I, get that some FS need memory, just like kernel and
userspace need memory to function. But to be honest, things
should fail or slow gracefully. Why in the world, regardless of
directory size, should I ever need to feed ZFS 10GB of RAM?
Notice I snuck in 2GB of that 12-32GB for kernels and users own
bloat. Yeah ok, I get FFS DIRHASH, if I don't feed it I simply get
a performance hit. But 12+ effing GB for ZFS and 80-90% free or
the system crashes hard? WTF people?!?!?! Where have we gone
wrong with this design? Where are the BSD principles???
I know I don't have a lot of time to characterize this issue, but
I say this because we often keep seeing "add more ram" as the
first/common fix, well that's not a real BSD solution. Cheers, mates.
