This one: https://metrics.torproject.org/rs.html#details/D00795330D77C75344C54FB8800531FAB3C40FBE 1core, 2GB RAM, 10GB Network You need bandwidth, _unlimited_ bandwidth.

Why not just a single > relay running with a large capacity? see above (multicore) These are very powerful servers. Mostly their own, in colocation. 1x10G, 2x10G or more network connection, 64 or 128 CPU cores 256-512 GB RAM and _unlimited_ bandwidth. In addition usually their own ASN. To advertise an AS via BGP, at least a /24 (255 IP's) is required. That's why I keep asking when we'll finally be able to run IPv6 only relays. /24 IP + ASN approx. 5000 EUR/(1st)year. (Only via waiting list & if never received an IPv4 allocation) /48 IPv6 + ASN approx. 100 Eur/year. https://www.ripe.net/manage-ips-and-asns/ipv4/ipv4-waiting-list > Also, is there a requirement for the > number of relays per core?

Rule of thumb - one instance per core. -- ╰_╯ Ciao Marco! Debian GNU/Linux It's free software and it gives you freedom!
