Your Dashboard Is Lying to You (And Polling Is Why)
Every five seconds, your frontend fires a request. The server wakes up, queries the database, serializes the response, and sends it back. Most of the time, nothing has changed. You just burned CPU cycles, network bandwidth, and a user's patience to confirm that the world is exactly the same as it was five seconds ago.
This is polling. It's the duct tape of real-time UX, and it's time to pull it off.
The Actual Problem With Polling
The UX issue is obvious: a dashboard that refreshes on an interval never feels live. There's always a lag window where stale data sits on screen while something critical already happened in the database. But the less-discussed problem is the compounding server load. Fifty users polling every five seconds is 600 requests per minute just to check if anything is new. Scale that up and you're paying for infrastructure to serve "nothing changed" messages at volume.
