Is that 2.2 million CIDRs, or actual addresses?

I use IPFW with tables for about 20k CIDRs. I don't see any significant server load. It seems to me nginx has a big enough task that it makes sense to offload the blocking to something that is more tightly integrated to the OS. 

At a bare minimum, block OVH and Hetzner. People bash the Russians and old Soviet block countries for hacking, but OVH and Hetzner are far worse.

We are blocking 2.2 million addresses, however, we do it at the firewall/router (pfsense pfBlocker).

Ultra fast.
