Well, the expectation is quite high -at least from my side :-)-.
We struggle with stable/10 boxes and ZFS since they are introduced in 
our environment, while stable/9 goes nicely under the same workload.
OS 10 swaps a lot to allow ARC to grow and without swap space, it starts 
killing random processes after 20-30 days, depending on how much RAM it 
has and how big I set the arc_max size (without it, the situation is 
even worse).

I wonder, nobody uses stable/10 with ZFS?
