If the error rate is not zero, you have an increased error rate.
In linux, you just do this:
sudo /sbin/ifconfig -a | grep errors | gre

I'll try an export/import and scrub of the receiving pool and see what that
does. I can't take the sending pool offline to try that stuff though.

The standard answer is mbuffer. I think you should ask yourself what's

FWIW I found netcat over at CSW.

mbuffer itself very specifically ends with a broken pipe error. Very quickly
with s set to 128 or after sometime with s set over 1024.

I have no idea why mbuffer fails. Changing the -s from 128 to 1536 made it take
longer to occur and slowed it down bu about 20% but didn't resolve the issue.
It just ment I might get as far as

I have no idea why mbuffer fails. Changing the -s from 128 to 1536 made it take
longer to occur and slowed it down bu about 20% but didn't resolve the issue.
It just ment I might get as far as 2.5gb before mbuffer bombed

I've tried ssh blowfish and scp arcfour. both are CPU limited long before the
10g link is.
I'vw also tried mbuffer, but I get broken pipe errors part way through the
transfer.
I'm open to ideas for faster ways to to either zfs send directly or through a
compressed file of the zfs send output.
