What is the maximum response time you should aim for the completion of the whole task?
Complete any actions initiated by the user within 100ms. The user should feel the interaction is instantaneous. The 100ms goal is still in the range of a fast and instant response. 100ms is the time the whole task should take. The time you should aim is 50ms. This budget is necessary because, for any interaction, the browser has to do some extra work.
