I have an application that iterates through snapshots sending them to
a remote host. With a Solaris 10 receiver, empty snapshots are received
in under a second, but with a Solaris 11 Express receiver, empty
snapshots are received in 2 to three seconds. This is becoming a real
nuisance where I have a large number of snapshots in a filesystem that's
unchanged.
For example:
receiving incremental stream of export/vbox@20110927_1805 into
backup/vbox@20110927_1805
received 312B stream in 3 seconds (104B/sec)
receiving incremental stream of export/vbox@20110927_2205 into
backup/vbox@20110927_2205
received 312B stream in 2 seconds (156B/sec)
The change looks to be increased latency, bigger snapshots still appear
to be received at the same speed as before.
Does anyone know what has changed to cause this slowdown?
