if we would get multithread support, this would boost the bandwith that is avaible, there i'm sure. All my relays run in CPU limit because i don't think wasting even more ipv4 addresses is great, today you get more and more cpu cores that is not linier with the IPC increase.
E.g. you have a Server with 2x E5-2683 v3 v3 and a 10 Gbit/s pipe you would need atleast 14 IP's to use most of the CPU. And every IP's gets blacklistet, with that much Tor nodes in the same /24 maybe the entire /24. So most ISP's wouldn't be happy with that and with the IPv4 shortage this days im also not very happy with that. We really shouldn't waste more IPv4 IP's then needed and the only solution is to change the max amount of Tor Processes from 2 to a higher number or move to IPv6 or get multithreading working.

You're missing the point. It would be trivial for a multibillion dollar organization to sybil attack Tor if you add excessive restrictions.
If you look at the numbers isis posted, all relays below the median contribute less than 3% of the overall bandwidth. I think cutting all of them off might be overkill, but even if you did, you would not make a Sybil attack appreciably harder.
