Maybe I'm naive, but I would imagine that any raspberry pi could run an IRC server with 10,000 users... Surely 10,000 Users each on average receiving perhaps five 50 byte messages per second (that's a very busy chat room!) is a total bandwidth of 2.5 megabytes per second. And the CPU time to shuffle messages from one TCP connection to another, or encrypt/decrypt 2.5 megabytes per second should be small. There is no complex parsing involved - it is literally just "forward this 50 byte message into this list of TCP connections". If they're all internal/authed users, you can hopefully assume nobody is deliberately DoSing the server with millions of super long messages into busy channels too.

IRC servers are single threaded. You have contention at that point.

  Some of the bigger irc channels have thousand users and this was in the day of 128MB of ram.

    Sure it's possible. But you need to test... For example there was/is a 1k file descriptor limit per process in a lot of distributions..

Let's not forget IRC channels can be split between servers too - don't wanna complicate the backup system too much but this is in the original design of IRC.
