It isn't one person's experience with the UI. It is everyone's. If you don't think Slack is slow then you have forgotten what "slow" means. It is a chat program. It is incredibly simple. It is not doing anything complicated. We have gigabit internet, CPUs with multi-GHz clocks and high IPC rates, NVMe 4 SSDs that load data from disk almost instantly. It should open in milliseconds, not several seconds. That it ever takes a noticeable amount of time to do anything reveals deep flaws in Slack's engineering culture, because it shows they just don't care about performance at all. If they had "good infra people" then their program wouldn't sit and spin for seconds, ever.
