I have some optimizations in my plans. I'd need a server to test. Wanna help around?

@hyperxpro , Better and for maximum performance will be XDP, so if you have time and desire, rewrite it in XDP.
Rust + XDP can also be an option, I see that you have some repository (game oriented) already.

@Gawnz1 Indeed, I do plan for XDP but redbpf is no longer being maintained. I have to use a new Rust library to make things working again.

That's nice to hear! I usually use LibXDP / LibBPF with C, since I don't know rust. You might take a look, if it fits for your project/language (If there is nothing for rust yet).
