Replication task running at 60MB/s on 100Gbit network

Hi, dear FreeNAS users !

I'm struggling with file transfer between two FreeNAS boxes, ServerA and serverB over NFS.

I started testing NFS after noticing that a snapshot replication was running at ~60 MB/s (on 100Gb network).

I will test other share possibilities after I'm done with those tests.

I'm looking for help identifying the bottleneck.
