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.
