  2. Latency (engineering) - Wikipedia

    en.wikipedia.org/wiki/Latency_(engineering)

    Latency, from a general point of view, is a time delay between the cause and the effect of some physical change in the system being observed. Lag , as it is known in gaming circles , refers to the latency between the input to a simulation and the visual or auditory response, often occurring because of network delay in online games.

  3. Latency - Wikipedia

    en.wikipedia.org/wiki/Latency

    Latency (engineering), a measure of the time delay experienced by a system Latency (audio), the delay between the moment an audio signal is triggered and the moment it is produced or received; Mechanical latency

  4. Speedup - Wikipedia

    en.wikipedia.org/wiki/Speedup

    Speedup can be defined for two different types of quantities: latency and throughput. [1] Latency of an architecture is the reciprocal of the execution speed of a task: = =, where v is the execution speed of the task; T is the execution time of the task; W is the execution workload of the task.

  5. Cache performance measurement and metric - Wikipedia

    en.wikipedia.org/wiki/Cache_performance...

    The execution time is the time for a cache access, and the memory stall cycles include the time to service a cache miss and access lower levels of memory. If the access latency, miss rate and miss penalty are known, the average memory access time can be calculated with: = +

  7. Lag (video games) - Wikipedia

    en.wikipedia.org/wiki/Lag_(video_games)

    Instead, the latency involved in transmitting data between clients and server plays a significant role. Latency varies depending on a number of factors, such as the physical distance between the end-systems, as a longer distance means additional transmission length and routing required and therefore higher latency.

  8. Memory latency - Wikipedia

    en.wikipedia.org/wiki/Memory_latency

    Memory latency is the time (the latency) between initiating a request for a byte or word in memory until it is retrieved by a processor. If the data are not in the processor's cache , it takes longer to obtain them, as the processor will have to communicate with the external memory cells.

  9. Network performance - Wikipedia

    en.wikipedia.org/wiki/Network_performance

    The speed of light imposes a minimum propagation time on all electromagnetic signals. It is not possible to reduce the latency below = / where s is the distance and c m is the speed of light in the medium (roughly 200,000 km/s for most fiber or electrical media, depending on their velocity factor).
