    Is there an expectation on this being merged forward and/or MFC'd?


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?

Please try to upgrade to r265945 or later.


   Thanks for the pointer, I will try it!
