Law of Interface Responsiveness

Changes in response time between 0 and 1 seconds don't matter, because they're too small to notice.

Changes in response time between 1 and 10 seconds matter a lot, because the user will get bored waiting for it to finish.

Changes in response times above 10 seconds again don't matter, because the user is less likely to be sitting there waiting for it to finish, and will have gone and done something else.
