> For example, if a feature is used every day for a year by 10,000 people, speeding it up by 200ms is worth over a month of developer time (200ms for 10,000 people over a year is 203 hours of time wasted, which is about 25 8-hour days, or five 40-hour weeks).
Is your company ready to pay $10-20k to its software supplier to save 200ms per person ? Rationally it may be a good idea, but I sincerely doubt anybody would pay for that.

What if those milliseconds are the ones that keep more users on your site, like in Amazon's famous search bar story?
