So I know this mod called TCPNoDelay, it is created by the owner of Kohi. What it does is, it opens a special connection, to get a better connection to a server. BUT, it can be used to give a big advantage, only for windows users tho! I will provide down below what advantages it can give, and how it can be used for it! Better reach. Less KB (Knockback/Velocity) It's not really that much, but still, it can give a big advantage with less knockback, and better reach. So, how does it work? It works with using RegEdit a registry tool for windows. You can create values for it, and for this, it creates a value in a registry I can't really remember. But it creates a value called TcpNoDelay. You can both buy values online, or get them free. Many people might not get how this can give an advantage in PvP. So here is it is With less knockback, you won't take as much knockback as usual. If you don't know what knockback is, it is when people hit you, and you get knocked backward. With a better reach, you get 1-2 block(s) extra reach, which means you can hit further than usual. The normal reach for Minecraft is 3-4 blocks, depending on the servers configuration.
