How many consecutive connections can enet handle?

[elieobeid7]

I'm using Godot game engine to create a multiplayer game, it supports UDP, TCP and websockets. According to my research UDP is the only one reliable, they use Enet.

I didn't get a decisive answer from godot community on how many consecutive connections Enet can handle, many create a new server instance using docker per room, I don't like that

I want to have 8 players per room, how many consecutive connections can Enet handle before that I have to create a new docker instance? If there's no good answer, I'd like to know the safest bet before creating an instance.

It can handle 4K connections on a single host.

Thank you so much, a single host meaning a single docker container right? not a single server?

How to scale enet? is docker the way to go?

ENet has nothing to do with docker at all. I have no idea what Godot has done that would suddenly require docker. ENet is only a UDP protocol.

I meant to ask, if you need to handle more than 4k, what would you do? they use docker to handle more than 4k connections that's all. In any case, if you need to handle 5k, you create a cluster right?

I'm closing this issue, you solved it so fast, thank you.

Trying to do more than 4K connections on a single host would not really be that efficient, because you are stressing one single OS process trying to deal with all the load of them. So you might want to reconsider your networking architecture so that those connections get split over to multiple hosts/servers and so they you can take advantage of parallelism.
