For questions pertaining to the measurement or improvement of latency in a system.
In computing terms, latency describe the time it takes to perform an action. Low latency implies this should be particularly short. It is usually in the range of timings which cannot be seen, only measured.
Low Latency implies that there is a measure for the latency of critical portions of the system and that it should meet this latency requirement a high percentage of the time e.g. 99%, 99.9%, 99.99% or worst case.
This could be any where from 10 nano-second to 100 milli-seconds depending on the context.
Questions which tag low latency should give measurable timings and percentage to reach that as the solution to follow is very dependant on these measures.
Without a latency measure to go by often the simplicity of the solution should be the target which will produce quick application with minimal complexity/effort.
