Ignoring transmission time for a moment, the response time is the sum of the service time and wait time. The service time is the time it takes to do the work you requested. For a given request the service time varies little as the workload increases – to do X amount of work it always takes X amount of time.
1 millisecond – nerve conduction velocity (neuron signal firing) happens on the order of milliseconds; 1.000692286 milliseconds – time taken for light to travel 300 km in a vacuum; 1 to 5 milliseconds – typical response time in LCD computer monitors, especially high-end displays; 2 milliseconds – Shift time for a modern Formula One car ...
In LCDs it is the number of times the image can be changed per second, expressed in hertz (Hz). Determines the maximum number of frames per second (FPS) a monitor is capable of showing. Maximum refresh rate is limited by response time. Response time is the time a pixel in a monitor takes to change between two shades. The particular shades ...
Response time on chronometric tasks are typically concerned with five categories of measurement: Central tendency of response time across a number of individual trials for a given person or task condition, usually captured by the arithmetic mean but occasionally by the median and less commonly the mode; intraindividual variability, the ...
Response time (technology), the time a generic system or functional unit takes to react to a given input Display response time, the amount of time a pixel in a display takes to change; Round-trip delay time, in telecommunications; Emergency response time, the amount of time that emergency responders take to arrive at the scene of an incident ...
The response time is the sum of three numbers: [3] Service time - How long it takes to do the work requested. Wait time - How long the request has to wait for requests queued ahead of it before it gets to run. Transmission time – How long it takes to move the request to the computer doing the work and the response back to the requestor.
0.01 ms [10] to less than 1 μs, [11] but limited by phosphor decay time (around 5 ms) [12] 1–8 ms typical (according to manufacturer data), older units could be as slow as 35 ms [13] Typically less than 0.01 ms, as low as 2 μs, [10] [14] but limited by phosphor decay time (around 5 ms) Estimates varying from under 0.01 ms to as low as 1 μs.
Synthetic testing is useful for measuring uptime, availability, and response time of critical pages and transactions (how a site performs from all geographies) but doesn't monitor or capture actual end user interactions, see Website monitoring. [3]
