Network speed reporting issues

I'm doing a replication of a large dataset between two CORE servers on the same network switch. Both have Gigabit NICs. This is typically what I am seeing speed-wise on the Interface card on the sending server dashboard.

On TC 2.0.2 and the latest nightly (middleware version 20210914), this is what I see on the System and Net Used cards.

A couple of observations:
  1. The network speed figures on TN CORE (108.64 MiB/s) and the TC Net Used card (avg. 850 Mib/s = 106.25 MiB/s) match.
  2. The speed reported on the TC system card does not marry up with the speed reported on the other cards.
  3. A second issue is the inconsistent use of units between the TC System card and TC Net Used card. The System card uses Gigabit rather than Gibibit.
What alerted me to the issue is that I can't be getting more than the theoretical maximum of 1 Gb/s on a Gigabit NIC so network speed reporting on the TC system card must be incorrect.

Reported under JIRA ticket TC-1829.
