It's not about speed in terms of absolute cumulative time. It's about the interleaving, the user experience of latency, and the effect that has on our cognition.
A few ms of noticeable latency here and there, a few hundred ms freeze every once in a while, it's maybe an extra minute per day in clock time. If it was just a 1 minute startup penalty, that would be different. But this 60,000 ms is split up throughout the working day into hundreds of small pauses, making the system feel laggy and unpredictable. If you're lucky, it's merely a subconscious drag on your attention. If you're unlucky it will, have you constantly breaking concentration to wonder "is my editor frozen? Oh wait, never mind." Hundreds of times a day.
Now contrast that to a text editor with literally zero instances of noticeable lag. It's not that it has zero latency, it's that the I/O latency on modern hardware is faster than our fingers and eyes can work. So we don't experience it.
Hundreds of noticeable pauses versus zero pauses. Once you cross the threshold below which our fingers type and brain can read, you're lag free. Getting a faster text editor doesn't just slightly improve the lagginess, it completely solves it.
