Something must've changed in either SSH, or the ZFS receive bits to cause this, but sadly since I upgrade my pool, I cannot roll back these hosts :(
I'm not sure that's the best way, but to look at how ssh is slowing down the transfer, I'm usually doing something like that:
zfs send -R data/vo...@2009-12-14_01h44m47 | pv | ssh hex "cat > / dev/null"
I usually get approximately 60 MB/s.Changing the cipher can enhance the transfer rate noticeably: "-c arcfour" gives an extra 10 MB/s here. If you found that ssh is what is slowing down the transfer, maybe another cipher than the default one can help.
