If you're running Solaris 11 or pre-2015 OmniOS, then the old write throttle is

pre-2015 can be clarified a bit: r151014 and later has the modern ZFS write
throttle. Now I know that Stephen is running later versions of OmniOS, so you
can be guaranteed it's the modern write-throttle.
Furthermore, anyone running any OmniOS EARLIER than r151014 is not supportable,
and any pre-014 release is not supported.

…and I am actually fine with the new controls/tunables, so there's
aboslutely no fuss here. ;) Plus, I actually understood, how both work,
which is a plus…
Cheers,
Stephan
