What is acceptable response time for Web applications?

A web response time ranging between 200 milliseconds and 1 second is considered acceptable as users still likely won't notice the delay. For better user satisfaction, you should take the time to optimize it. Any response time over 1 second is problematic and needs to be fixed.

What is the response time threshold where users notice a delay in interactive applications?

A delay of 0.2–1.0 seconds does mean that users notice the delay and thus feel the computer is "working" on the command, as opposed to having the command be a direct effect of the users' actions.

What is high response time?

A high response time means that requests from applications to a volume on a cluster are taking longer than usual. The cause of the high response time could be on the cluster itself, due to contention on one or more cluster components.

What is UI response time?

10 seconds

This is the limit for the user's short-term memory. The users start to lose information and thus will not be able to resume the interaction very smoothly when the computer finishes the task. Special feedback is required for this response time.
