I am really confused about the point you're trying to make. 150tok/s is slow, but so is 9000tok/s? Or they're both fast? Or 150tok/s should be enough?
probably no number you come up with will be adequate for very long. [edit] it's a reference to this possibly apocryphal prediction https://www.computerworld.com/article/1563853/the-640k-quote...
The "640k should be enough for anyone" quote (even if Gates didn't exactly say it) is making the point is that _right now_ we have no idea about what our future needs and capabilities will be, we can't imagine what "should be enough" will be
640k was enough ... in 1981 ... almost fifty years later is 50,000 lower than a standard off the shelf PC now
