Slack desktop app consumes excessive RAM and CPU on laptops
Knowledge workers running Slack alongside development or creative tools experience significant performance degradation due to the app's high memory and CPU footprint. This is a structural Electron framework issue that Slack has not resolved despite repeated user complaints. It affects the majority of Slack's 32M+ desktop users and compounds on lower-spec machines.

Similar Problems
surfaced semanticallySlack 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 Linux App Excessive CPU Usage Causes Freezes
Slack consumes excessive CPU on Linux, freezing during screen sharing and terminal use. Forces users to web UI instead.
Slack Login Failures and Upload Interruptions Waste Work Time
Users report frequent login issues and upload failures in Slack that consume significant time. These are likely transient reliability bugs rather than a persistent structural problem.
Slack Desktop Client Too Resource-Intensive on macOS
The Slack desktop app on macOS consumes excessive CPU and memory, causing system slowdowns during normal use. The Electron-based architecture is the root cause — a structural constraint not easily patched. Enterprise users running Slack alongside other heavy tools feel the impact most acutely.
Trello web app uses excessive memory and slows down multi-app setups
Trello consumes significant RAM when running alongside other applications, causing system slowdowns that force users to close the app. This is particularly problematic for users on lower-spec hardware or with memory-intensive workflows. The issue is a performance regression rather than a feature gap.
