Which translates to a little over 18 MB/sec. and 600 files/sec. That
would mean almost 16 hours per TB. Better, but not much better than
NBU.
I do not think the SE-3511 is limiting us, as I have seen much higher
throughput on them when resilvering one or more mirrors.
Any thoughts as to why I am not getting better throughput ?
With Solaris 10U7 I see about 35MB/sec between Thumpers using a direct
socket connection rather than ssh for full sends and 7-12MB/sec for
incrementals, depending on the data set.
