Greg,
you’re probably thinking of znapzend,

by Tobias Oetiker et al.
In addition to maintaining local snapshots, it can backup to a local or remote
destination over mbuffer or ssh with zfs send/receive.
It stores its configuration as zfs properties and comes with

As you may realize, most versions of OS X may only be virtualized on Apple
hardware per the license agreement. (An exception is Snow Leopard Server, which
was ~ $500 back in the day.)
This is probably one reason why not much has been written about running OS X on
SmartOS – though
Ian,
I agree that something is wrong. The whole point of using those fancy Intel
NICs should be to reduce the CPU load, right?
Here is a technote from HELIOS, makers of the enterprise AFP server EtherShare,
about 10GbE tuning:

Ian,
Right now I'm fighting with my Finder/AFP/netatalk/getcwd() performance issues,
which are a landmine, so the 10GbE slowdowns are the least of my worries. But
here is what I did find out.
It helps to tune the following TCP stack parameters:
# ndd -set /dev/tcp tcp_recv_hiwat 40
not, but it comes up often
enough that I prefer to check.)

Dewey,
You are absolutely right. If I actually put
set ncsize=nnn
in my copy of etc/system on the boot USB key, the kernel picks up the new value
as shown by
# echo ncsize/D | mdb -k
even though /etc/system appears unchanged. Well, I guess I was being too
careful this time.
Thanks!

I'm trying to modify /etc/system, specifically to set ncsize to a higher value
than the default in order to get a larger DNLC and improve the DNLC cache hit
rate.

do it with SunSSH?
