Slack consumes excessive RAM and slows laptops during huddles
Users report Slack uses a large amount of RAM and noticeably slows their laptop, especially while in a huddle call. This is a widely-experienced performance problem given Slack's broad daily-active-user base.
Slack's Resource Usage and Huddle Feature Need Improvement
A user describes Slack as heavy software to run and suggests its huddle (voice/video) feature could be improved. A brief, low-detail performance and feature complaint rather than a significant blocker.
Slack Desktop App Consumes Excessive RAM and CPU on Laptops
Slack's Electron-based desktop application is notorious for high memory and CPU consumption, degrading performance on laptops especially when multiple workspaces are open. This forces users to close Slack to reclaim system resources or accept reduced responsiveness across other applications. The issue has persisted for years and is a known architectural constraint of the Electron framework.
