Good news fellow Slack users, your productivity just got bumped by the perf gods of Slack thanks to their continued efforts and focus on the desktop app’s performance. Slack is unveiling a new version of its desktop app for Windows and macOS today that promises big performance improvements. Slack has rebuilt its desktop app to focus on speed, and the company claims Slack will now launch 33 percent faster than before. The Slack app will even use 50 percent less RAM than before, according to the company. Slack has been working on this overhaul for two years, slowly modernizing parts of its code along the way. While the desktop apps still run on Electron, all of the UI parts have been rebuilt using React to fix some of the shortcomings of the existing Slack app.
