Operating Systems Solaris zfs send receive performance issues Post 302724069 by achenle on Wednesday 31st of October 2012 07:18:26 AM

OP says mbuffer isn't going to be allowed.

Running
Code:
zfs send ... > /some/file/name

where the file is on a known FAST file system would help isolate if the issue is in the send or the receive. Run the send, see how fast it is, then run receive off that file and see how fast that is.

Maybe some useful data points can be generated.

And there might even be some way to use a file and some standard utilities to duplicate the functionality of mbuffer. Maybe something as simple as starting the send to a file, waiting a few minutes, then starting the receive might work if the send always runs faster than the receive and the receive won't hit EOF before the send is done.
