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.

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).

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.

Sorry, yes. It is straight;

# /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
When we tested Solaris 10 10/08 -> Solaris 10 10/08 these were the
results;
zfs send | nc | zfs recv -> 1 MB/s
tar -cvf /zpool/leroy | nc | tar -xvf - -> 2.5 MB/s
ufsdump | nc | ufsrestore -> 5.0 MB/s
So, none of those solutions was usable with regular Sol 10. Note most
our volumes are ufs in
zvol, but even zfs volumes were slow.
Someone else had mentioned the speed was fixed in an earlier release,
I had not had a chance to
upgrade. But since we wanted to try zfs user-quotas, I finally had
the chance.

To finally close my quest. I tested "zfs send" in osol-b114 version:

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

We finally managed to upgrade the production x4500s to Sol 10 10/08
(unrelated to this) but with the hope that it would also make "zfs
send"
usable.
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 next
version of Solaris 10 will have the improvements.

Hello Jorgen,
If you look at the list archives you will see that it made a huge
difference for some people including me. Now I'm easily able to
saturate GbE linke while zfs send|recv'ing.
Since build 105 it should be *MUCH* for faster.

Can you give any details about your data set, what you piped zfs
send/receive through (SSH?), hardware/network, etc?
I'm envious of your speeds!
