mbuffer comes in handy when you do zfs send / recv over a network. You
can put it in between the send and recv processes and it will provide a
buffer that makes up for pauses in network or disk IO.

Description from the mbuffer website:

mbuffer is a tool to buffer data streams. Its special feature is to show
the I/O rate and summary to the user. This was firstly the main reason I
developed it. It is especially useful, if you are writing backups to
fast tape drives or libraries. Those drives tend to stop and rewind if
they have a buffer underrun. This so called tape screwing reduces the
lifetime of the motors. mbuffer can prevent buffer underruns, if used
correctly and speed up the whole backup process.
