Zpool version 11, introduced improved scrub performance
I tested with Bonnie++ and it reports about 200MB/s.
The pool version is 22 (SunOS solaris 5.11 snv_134 i86pc i386 i86pc Solaris)
I let the scrub run for hours and it was still at around 10MB/s. I tried to
access an iSCSI target on that pool and it was really really slow (about
600KB/s!)

Too bad then, I can't afford a couple of SSDs for this machine as it's just a
home file server. I'm surprised about the scrub speed though... This used to be
a 4x500GB machine, to which I replaced the disks one by one. Resilver (about
80% full) took about 6 hours to complete - now it's twice
Hello, I'm trying to figure out why I'm getting about 10MB/s scrubs, on a pool
where I can easily get 100MB/s. It's 4x 1TB SATA2 (nv_sata), raidz. Athlon64
with 8GB RAM.
Here's the output while I cat an 8GB file to /dev/null
