Hey,
so i created a snapshot, ( zfs snapshot blah/mail/[EMAIL PROTECTED] ) and
then i tried to send it accross the network, ( zfs send
blah/mail/[EMAIL PROTECTED] | ssh [EMAIL PROTECTED] zfs recv
blah/mail/[EMAIL PROTECTED] ) and i only seem to be getting 2 - 4 mb /
s... unless i'm missing somthing. ( it's a gbe cross over from one
v20z, to another )
I'm getting the figures from the zfs list i'm doing on the destination...
so, is there a faster way ? am i missing somthing ?
That's almost precisely the performance I got sending a bunch of data
across gbe via SSH myself -- but I was just doing an scp. And it was
a slow processor, which probably was the actual limiting factor. So
my suspicion is that ssh encryption is your limiting factor in that
test.
An easy test -- try rsh instead of ssh if you can. Remember ssh is
encrypting everything it carries. That'll tell you if the problem is
network performance, encryption overhead, or ZFS behavior.
For that matter, do the zfs send to /dev/null; that'll let you measure
the inescapable minimum ZFS part of the time.
