> hundreds of milliseconds. Yes, there are a few specialized domains where this will matter. No, you probably don’t work in one.
This is funny to me, because I would think that for hundreds of milliseconds, anything user-facing is impacted. It's on the order of the human reaction time (~200ms). That's noticeable delay.
I do not work in frontend, so perhaps I am misguided. But I have had bad user experience using apps with even 100ms delay that require a lot of input (for example using excel or something in a streaming VM).
You are not misguided. Physiology is mostly intangible but consistent. Many of the comments here willingly ignore that “yes but my use case is different and my users are patient”. Their brain will still disconnect quickly and be frustrated.
