iPerf3 Bandwidth Results

Good morning, before we purchase any network upgrades we want to gather some bandwidth results. Upon using iPerf3 today, my results directly to the file server were good, avg. 930+ Mbits/s on a 1Gbe hardware infrastructure, however when I put iPerf3 into UDP mode the results were quite drastic, my bandwidth went to 1.05Mbits/s. This cannot be normal.

Seems to be a known phenomenon: performance - Why is UDP slower than TCP on Ubuntu Server? - Server Fault

Well onething I discovered iPerf3 defaults to 1Mbit/s for testing, I needed to add the switch -b 0 to make it default to what TCP uses, results ended up being slightly faster than TCP.
