What is UI response time?
The threshold of human perception. “0.1 second is the response time limit if you want users to feel like their actions are directly causing something to happen on the screen… Thus, to create the illusion of direct manipulation, a user interface must be faster than 0.1 second.”
What response time would be considered by a user as an instant response?
0.1 second
The basic advice regarding response times has been about the same for thirty years [Miller 1968; Card et al. 1991]: 0.1 second is about the limit for having the user feel that the system is reacting instantaneously, meaning that no special feedback is necessary except to display the result.
What is my screen response time?
Response time for monitors is the time it takes to shift from one color to another. This is usually measured in the time it takes to go from black to white back again to black expressed in milliseconds (ms). However, there is also gray-to-gray (GtG) and sometimes even just black-to-white.
What is the ideal response time for a website?
As you can see the location you are accessing the website plays a significant role in the response time, but the average is around 3.5 seconds. “The lower, the better” rule applies here as well, of course, but if your site is able to fully load under 2 seconds, that is a great result.

How long should a user wait for a delay?
Normally, no special feedback is necessary during delays of more than 0.1 but less than 1.0 second, but the user does lose the feeling of operating directly on the data. 10 seconds is about the limit for keeping the user’s attention focused on the dialogue.
