Similar Problems
surfaced semanticallySlack High Memory Usage and Unreliable Notifications Reduce Reliability
Slack consumes excessive system memory and notification delivery is inconsistent, causing users to miss messages or experience sluggish performance. The Electron-based desktop client is a known resource bottleneck that Slack has not fully resolved. Teams dependent on Slack for real-time communication cannot tolerate missed notifications from a tool positioned as their primary channel.
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.
Slack lags and becomes unresponsive in large workspaces
Slack performance degrades noticeably as workspace size grows, requiring constant manual refreshes to see new messages. This is a structural scalability problem affecting enterprise customers who depend on Slack as their primary communication layer.
Slack feature overload leads to low adoption and confusion
Slack ships so many features that users feel overwhelmed and end up ignoring most of the product. The cognitive overhead reduces effective adoption within teams. The problem is widely acknowledged but Slack and competitors actively address it.
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.
