Lol, there are some other relays with more traffic than I have but there's definitely a lot of traffic to my relay though!
I don't have a good enough self-hosted solution yet so hosting on a Hetzner VM atm.
I ran mine on a 5 USD/month until Jack showed up. Now it's running on a VM with 8 Intel vCPUs and 32 GB RAM. It works but IMO it's still way too slow.
