Hi Carsten,
thank you for your suggestion.
I had not time yet to test my script with netcat, but I will give
mbuffer a try!
I heard from that tool some time ago, but I did not think on it.

Hello,
thank you very much! With the "d" flag, the nc commands works very well!

Hi Florian,
I played with zfs send/reveive some time ago. One important thing I learned was
that netcat is not the first choice to use.
There is a tool called mbuffer out there. mbuffer works similar to netcat but
allows a specific buffer size and block size.
From various resources I found out that the best buffer and block sizes for zfs
send/receive seem to be 1GB for the buffer with a block size of 131073.
Replacing netcat by mubuffer dramatically increases the throughput.
The resulting commands are like:
ssh -f $REMOTESRV "/opt/csw/bin/mbuffer -q -I $PORT -m 1G -s 131072 | zfs receive
-vFd $REMOTEPOOL"
zfs send $CURRENTLOCAL | /opt/csw/bin/mbuffer -q -O $REMOTESRV:$PORT -m 1G -s
131072 > /dev/null
