Consensus weight is calculated using a relay's self-reported peak bandwidth
usage, and measurements from ~6 bandwidth authorities around the world.

The process is slightly different on some of the bandwidth authorities, because
we are migrating to a newer system.

There is detailed documentation here:

5/6 bandwidth authorities run torflow:

1/6 bandwidth authorities run sbws:

https://gitweb.torproject.org/torspec.git/tree/bandwidth-file-spec.txt#n656

Tor is a connection-oriented, reliable-transport, low-latency network, so it will
never use your full bandwidth capacity. If it did, latency would suffer.

Here are some initial steps for troubleshooting:
