Currently I am employing a large number of ipsets (about 30k+ subnets in
total) which hold IP subnets fetched from whatever the latest version of
the geoip database I have sourced and compiled.
I am aware that xtables also have the geoip target, though was wandering
what the performance is like compared to having the same IP subnets
loaded with ipset. Has anyone tested/compared these two matching methods?
I know the performance of iptables when it deals with large number of ip
addresses is absolutely abysmal, so never tried to use the geoip target,
so just wanted to see if that has changed?

The geoip target uses a bisection search, so the US database's
19000-something entries are testable in roughly 15 steps.
Since it does not need any extra structures, it only takes as much
kernel memory as the .iv0 file on disk.
