performance - Is there any standard for response times in desktop applications? -

-

a customer asks response times under second "dialog-based" applications. speaking our desktop applications getting data business server connected sql server.

usually 1 second ok us, have got forms take longer (up 2 or 3 seconds). know standards (or source) specifies should response times user? i've found many different informations, web pages , not desktop applications.

i read somewhere 3 seconds "magical" number. read "10 seconds rule" norman nielsen web pages. others speak "4 seconds" rule.

i have arguments customer "third party" ("as know, accepted limit specified in iso norm xx") :-)

thank you

even if actual performance of dialogs can not improved, can @ techniques may improve perceived performance of application. lazy loading, or asynchronously loading parts of dialog after it's shown may improve experience user , not require exceptional effort you. feedback on progress, may improve user's experience. may want test out ideas users, couple, see perceive problem, , @ techniques address specific issues.
