If TOR had fiver-level speed I'd be on all the time. The trade off is just too high.
I do use it frequently and do run a few relays, and that's probably the only way to improve it.
If it were simpler to run a relay on a provider that allows it, and it doesn’t cost much (say $10 a month) to give Tor users a little more speed, that’d be helpful. The last time I looked at the documentation, it seemed quite involved and complex (of course, I wouldn’t want the security of Tor users to be compromised due to any misconfiguration).
If there were something for Tor like Sandstorm for web apps or Algo for WireGuard, more people could run relays and help everyone.
Here's a giant list of hosts you can look into - https://community.torproject.org/relay/community-resources/g...
I spent maybe an hour researching based my in criteria. You can host just an exit (most helpful), or a couple of relays (aim for 100mbps+, and decent bandwidth). You can get a lot for $5/month for each relay.
