I’ve gotta hand it to the OpenSolairs guys – they’ve done a lot of good work. When I was running an (admittedly old) build of Solaris Nevada, my network throughput would top out around 22MB/s – which is pretty respectable for a RAIDZ1 pool on consumer-level SATA disks. I was moving some VM disks around, and noticed this:

root@vault:~# zpool iostat tank 30

Wow. Just wow.
