  • Discord uses Electron, which causes each channel to act like a browser tab, consuming excessive RAM.
  • CPU usage on macOS can exceed 100%, affecting system fluidity and causing the computer to overheat.
  • The platform implements automatic client restarts based on inactivity to free up RAM.

Discord Optimization

If you've ever felt like your MacBook is about to burst into flames or that the fan seems like it's going to take off while you're chatting, you're not alone. It's quite common. Discord consumes an absurd amount of CPU, sometimes exceeding 100% in the Activity Monitor, leaving the computer as slow as a turtle.

Many people are wondering if this is a one-off glitch on their own machine or a general software issue requiring a patch. The reality is that this is a recurring problem with the application, affecting both macOS and Windows users, primarily due to the underlying technical architecture.

The culprit: Electron's architecture

To understand why Discord is resource-intensive, we need to talk about Electron. Essentially, this app is a browser window disguised as a program that uses Node.js to run. This means that each server or message you load acts as if it were a separate browser tab.

The problem arises because, as you move between different channels, RAM usage steadily increases . It's not just Discord; other popular apps like WhatsApp and Microsoft Teams (the latter using WebView2) suffer from similar issues, as this framework is very convenient for developers but quite inefficient for the user's hardware.

How is Discord trying to resolve this chaos?

The company is aware that RAM consumption can skyrocket from a reasonable one gigabyte to four gigabytes, which is absolutely insane. Therefore, they've launched an experiment to automatically restart the client when they detect that the memory is at its limit.

Note that this doesn't mean the app will suddenly close while you're talking. For the restart to occur, certain very specific conditions must be met.

  • The user must carry at least 30 minutes of inactivity (without touching a mouse or keyboard).
  • There shouldn't be any. voice call or video call active at that moment.
  • The application must have been open during at least one hour.
  • This automatic cleaning process It doesn't happen more than once. every 24 hours.

Although this solution has generated considerable criticism on social media platforms like X, Discord insists that it is a temporary measure while they develop deeper optimizations to reduce the impact on the system, especially in modern environments such as Windows 11 or current versions of macOS.

For those experiencing excessive CPU usage on their Mac, it's vital to monitor for interfering background processes and remember that, being a web-based app, refreshing the application sometimes helps release that accumulated load that the system doesn't manage well on its own.

Ultimately, Discord's high resource consumption is due to its use of the Electron framework, which causes RAM and CPU usage to spike when loading multiple channels, forcing the company to test automatic restarts based on user inactivity to try to mitigate the impact on system performance.
