I cant believe I read Slack and fast in one sentence.

We use mattermost and its mostly OK to the point i'm willing to use it which cannot be said about Slack. Forcing me to have Slack open all the time was reason I left a job. It was unbearable.

It's surprising to read that. No one at work hates it so much, afaik. I wonder what's different about our channel lineup, usage habits, or anything else that is such a contrast to your experience.

I think is fast if you compare with the other products mentioned, I hope they get their shit together (Slack and Teams) and build a real native app that is fast and use a lot less ram.
