Ok, What am I doing wrong? Synology Snapshot Replication Speed Issue

Currently runnign snapshot replication between two synologies, Max speed of 125.1MB/s.

Connecting the 2 Synologies are 3 network cables, one synology plugged directly into another, bonded together with Balance XOR. I also tried IEEE 802.3ad Dynamic Link Aggregation but same speed.

Feels like it should be faster, am I doing something wrong?
