Newbie here. No network experience but already running 2 TOR instances: 1 TOR service + 1 bridge.
Never mix different relay types under one IP.
I would like to "upgrade" to TOR relays but have a few questions relating to hardware needs.
1core 2GB RAM is enough for an exit. This one: https://metrics.torproject.org/rs.html#details/D00795330D77C75344C54FB880053... 1core, 2GB RAM, 10GB Network You need bandwidth, _unlimited_ bandwidth. A relay easily has 50-100TB/month! Tor relay (=router) bandwidth is in + out!
I guess my fundamental question is what is the advantage of running multiple relays of the same type, on the same server?
Because C-tor is not multicore aware.
I see some operators running dozens of them, all in the same country, same ISP. 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.

Also, is there a requirement for the number of relays per core? (Maybe this is the answer to my question.) I know my bridge is currently keeping one core of my 2-core server constantly under load. Thank in advance.
Rule of thumb - one instance per core.
