Hello,

In a self hosted netbird I have 25 peers and already my CPU sometimes is at 50% because of the TURN/relay connexions.

How can I scale netbird, e.g have multiple relay servers?

Also, how do I know wether my relaying is currently happening through TURN or relay?

For example this relayed connexion:

{
  "fqdn": "axis-accc8ede87b2.netbird.selfhosted",
  "netbirdIp": "100.70.14.71",
  "publicKey": "123456UrZuTzecBWOZNSfVwnLPkd5oNaFX5PRL8sJyg=",
  "status": "Connected",
  "lastStatusUpdate": "2025-03-06T16:22:52.4087872+01:00",
  "connectionType": "Relayed",
  "iceCandidateType": {
    "local": "",
    "remote": ""
  },
  "iceCandidateEndpoint": {
    "local": "",
    "remote": ""
  },
  "relayAddress": "rels://netbird.domain.com:443",
  "lastWireguardHandshake": "2025-03-06T16:30:59.1114675+01:00",
  "transferReceived": 2213324,
  "transferSent": 105412,
  "latency": 0,
  "quantumResistance": false,
  "networks": null
}

Can I assume it's using the relay server because of the relayAddress ? How would a TURN relaying look like?

For the record here's how this client is connected (windows):

OS: windows/amd64
Daemon version: 0.37.1
CLI version: 0.37.1
Management: Connected to https://netbird.domain.com:443
Signal: Connected to https://netbird.domain.com:443
Relays:
  [stun:netbird.domain.com:3478] is Available
  [turn:netbird.domain.com:3478?transport=udp] is Available
  [rels://netbird.domain.com:443] is Available
Nameservers:
FQDN: stvs-pv-laptop1.netbird.stvs
NetBird IP: 100.70.63.243/16
Interface type: Userspace
Quantum resistance: false
Networks: -
Peers count: 18/24 Connected

I believe it will use the relay that responds the fastest. So which one you're using depends each time you connect.

Well, in self hosted mode there's only one relay... the one of your netbird server (the relay container).

I can't find documentation about how to spawn multiple relay servers, I guess I could load-balance it through traefik but that does not seem the correct way to do it.

You're not the first to have this issue. https://github.com/netbirdio/netbird/issues/3383

Basically, right now it's 100% capable to deploy numerous relays. You basicaly spin them up and have to manually edit the management.json on the management server, as outlined here https://github.com/netbirdio/netbird/issues/2566#issuecomment-2574431104. or https://github.com/netbirdio/netbird/issues/2566#issuecomment-2374767544

However, the official docs haven't been updated for this. Probably just needs someone to do it and submit a PR at this point.

Ah great, yeah it looks straightforward thanks 👍

I already have a PR about the Azure AD documentation, maybe I'll make one about this too.

@1nerdyguy: quick question, does it make sense to also scale the TURN servers or is it bound to disappear eventually?

I believe it's bound to disappear. ICE will stick around for session negotiation, AFAIK.
