Re: [IxDA] What makes an application feel fast?

Two factors were identified in a study several years ago (sorry, don't remember the reference):

1) The perceived complexity of an operation influences the user's expectations.

2) In a sequence of operations necessary to achieve a goal, the user grows increasingly patient.

No rocket science, but validated by the study.

This means that simple operations like moving a cursor, selecting an object, scrolling, etc. must be as fast as possible. Providing adequate feedback whenever instantaneous response is crucial.
