Websockets on App Platform, initial connection is slow, seconds not milliseconds

Posted on January 19, 2025

We’ve been using websockets on App Platform for a long time already, so a service that runs a websocket server, accessed through a path on the App domain.

However, recently I noticed that the initial connection of the websocket can be very slow, 10 or 15 seconds even. When logging, I can see that the request doesn’t reach the service. So in other words it’s not the service that is slow, it’s the App Platform load balancer.

I am now running the websocket server on a separate droplet, and connection time is never slow. But I rather run it inside App Platform for easier maintenance.

Is there something I can do to remedy or further troubleshoot this?

Hey @janmisker,

There would be a couple of things that you could check here:

  • Are you using the same amount of resources like CPU and RAM on both the App Platform and the Droplet?

  • Also on the Droplet, are you testing this with the same amount of data stored in your Database?

  • Is the App deployed in the same region as your database and Droplet?

If both the amount of data in your database and the amount of resources is the same, what I could suggest is reaching out to the DigitalOcean support team so they might be able to advise you further on this:

Hope that helps!
