iMac Late 2015 5k Retina - Slow ethernet Internet on Chrome/Edge

Hi,

I just upgraded my network to gigabit and running speed tests my iMac is always running slowly <100MB/s.

I finally narrowed it down to Chrome and Edge browsers. Safari runs the speed test at over 900MB/s.

Safari is not my preferred browser, does anyone know how I might fix this?

FWIW, if you are using speedtest.net, apparently chromium-based browsers do not like it. Chrome using FIOS speed test.
