Issue

On the source system, the outgoing.max_kbs is set to 45000, and on the destination system incoming.max_kbs is also set to 45000, but snapmirror still uses around 1Gb:
cluster_src::> options -option-name replication.throttle.outgoing.max_kbs 45000
cluster_dst::> options -option-name replication.throttle.incoming.max_kbs 45000
