Every time I start the discord app, it downloads updates. It was never the case when I opened discord app and it didn't start updating. Updating 7/13. Updating 1/4. There is always some update pushed, I think almost every day. Comparing the launch times of fully updated clients is kinda useless, as it will always take few minutes to update anyway when you are cold-starting it. Slow electron apps are just a skill issue. Yes it has a browser overhead, and it will use a bit more RAM, but the bare-minimum time required to spin up the underlying Chromium shell and Nodejs runtime environment is 100-300ms, everything on top of it is just application overhead aka skill issue. My slack client opens almost instantly all the time, and it's as responsive as any native application around, sometimes even greatly more responsive than some native apps made by Apple.

Not disagreeing with your general comment, but on my M3 Pro Slack takes 15+ seconds to start (usually snappy after that). I fucking hate it.
