Describe the Bug

I have a 4-core host running a Newt container and an Olm container. The Olm process continuously uses around 10% CPU, which is not extreme, but it's pretty much at the top of top, which strikes me as odd. Newt stays below 1%.

Environment

  • OS Type & Version: Debian GNU/Linux 12 (bookworm)
  • Pangolin Version: 1.14.1
  • Gerbil Version: 1.3.0
  • Olm Version: 1.3.0

To Reproduce

Can't report much details as it is, this is the compose file I have to deploy Olm (I'm not using host network on purpose):

secrets:
  olm_config:
    file: olm_config.json
services:
  olm:
    image: fosrl/olm
    container_name: olm
    restart: unless-stopped
    cap_add:
      - NET_ADMIN
    environment:
      CONFIG_FILE: /run/secrets/olm_config
      DISABLE_HOLEPUNCH: "true"
    secrets:
      - olm_config
    devices:
      - /dev/net/tun:/dev/net/tun

Besides the sensitive stuff, the JSON doesn't have anything out of the ordinary:

{
  "org": "",
  "userToken": "",
  "mtu": 1280,
  "dns": "192.168.50.1",
  "upstreamDNS": ["9.9.9.9:53"],
  "interface": "olm",
  "logLevel": "INFO",
  "enableApi": false,
  "httpAddr": "",
  "socketPath": "/var/run/olm.sock",
  "pingInterval": "3s",
  "pingTimeout": "5s",
  "disableHolepunch": true,
  "overrideDNS": false,
  "disableRelay": false,
  "tlsClientCert": ""
}

Expected Behavior

Less CPU usage, or at least a confirmation that more CPU usage is expected.

We are actually working on improving CPU usage for olm especially because of mobile devices! I hope to have some improvements in the next release.
