What Amethyst is doing is connecting to all the relays your follows have set as outbox (write) relays in their relay lists, so that Amethyst will more reliably display all of your follows' notes.

This can be a bit much when you have a less reliable and slower connection, though. In this case, you can tell Amethyst to stop connecting to all those relays by assigning a proxy relay in your relay settings. Then Amethyst will ONLY read from that relay. But you will want to use a relay that is likely to have all the notes you are interested in from all your follows.

Good options for proxy relays would be your own WoT relay, or an aggregator relay, such as nostr.land or filter.nostr.wine
