I run the non-exit relay: https://metrics.torproject.org/rs.html#details/855BC2DABE24C861CD887DB9B2E95... The relay run on a debian stretch machine with an i5-4670 at 3.8GHz with 4GB memory. CPU usage at 250Mbps traffic is around 40% of 1 core out of 4.
On April 1st my ISP doubled my bandwidth, from 250Mbps to 500Mbps. So far the Tor bandwidth authorities seems to not have picked up on all the new bandwidth. The observed bandwidth number has changed twice, increasing with small amounts.
How long does it take for the BW authorities to eventually observe a BW closer to 500Mbps. Weeks? Months? The reason I ask is that I wonder if I should run a second Tor instance or if the current one will be able to make use a a reasonable part of the 500Mps.
