I changed to try zfs send on a UFS on zvolume as well:
received 92.9GB stream in 2354 seconds (40.4MB/sec)
Still fast enough to use. I have yet to get around to trying something
considerably larger in size.

Au contraire...
From what I have seen, larger file systems and large numbers of files
seem to slow down zfs send/receive, worsening the problem. So it may be
a good idea to partition your file system, subdividing it into smaller
ones, replicating each one separately.

Am Di, den
Jorgen,
what is the size of the sending zfs?
I thought replication speed depends on the size of the sending fs, too not only size of the
snapshot being sent.

Dirk

So you recommend I also do speed test on larger volumes? The test data I
had on the b114 server was only 90GB. Previous tests included 500G ufs
on zvol etc. It is just it will take 4 days to send it to the b114
server to start with ;) (From Sol10 servers).

Can you give any details about your data set, what you piped zfs
Sorry, yes. It is straight;
# time zfs send zpool1/leroy_c...@speedtest | nc 172.20.12.232 3001
real19m48.199s
# /var/tmp/nc -l -p 3001 -vvv | time zfs recv -v zpool1/le...@speedtest
received 82.3GB stream in 1195 seconds (70.5MB/sec)
Sending is osol-b114.
Receiver is Solaris 10 10/08

Sender was a Core2Duo E4500 reading from SSDs and receiver was a Xeon

Yeeaahh!
That makes it completely usable! Just need to change our support
contract to allow us to run b114 and we're set! :)
Thanks,

There is no easy/obvious mapping of Solaris

Exactly how does build 105 translate to Solaris 10 10/08? My current
speed test has sent 34Gb in 24 hours, which isn't great. Perhaps the
