Execution time of large ip blacklist.txt

Any experience with implementing a ip blacklist.

I have gathered ip addresses of world by country.  The list of ip addesses <world X-US> is about 7mb of plain text.

Wondering about the server load and execution time to run the filter.

Any experience?
 

don't run it!

CSF has integrated country blocker but this is only for eg 1-5 countries, using it for more than that could cause overloads.

Anyway, why do you need it ?

Has CSF geoIP capabilities? Nice...

I wanna block Nigeria and Russia Joj0j0joo

why blocking whole countries since CSF/LFD will automatically block if they detect something

That was a Joke. Maybe a bad joke...

Blocking Nigeria because the known issue about trade with them (packet lost)
The joke is about that are TCP packets, not real shipped packets.

Blocking Russia because the hackers.
The joke is about put a firewall to block a real hacker.

The joke would be easy to understand with a "I wanna block Obama, from whatever Country it is trying to see my webpage"
