average latency

Average latency is the mean average time for a message to be passed from one point to another - the lower the better.

Any words on average latency you've experienced?

There are many use cases where predictability of latency in message delivery is as, if not more important than a low average latency.

High latency peaks have negative effects on most network applications which can adapt to average latency by allocating corresponding size of memory as buffer.

Buffer enables some applications such as stream videos to run smoothly even with high average latency, but it cannot protect us from high latency peaks.

It may make sense to separate read latency and write latency, and in case of sequential access storage, minimum, maximum and average latency.

In this case the random nature of the angular displacements goes away, the average latency returns to 1/2 revolution, and a saving of up to 50% in latency is achieved.

Average rotational latency is shown in the table below, based on the statistical relation that the average latency in milliseconds for such a drive is one-half the rotational period.

As long as most memory accesses are cached memory locations, the average latency of memory accesses will be closer to the cache latency than to the latency of main memory.

For example, in 2009 the London Stock Exchange bought a technology firm called MillenniumIT and announced plans to implement its Millennium Exchange platform which they claim has an average latency of 126 microseconds.

If the L2 cache still comes up empty, Penryn has no choice but to head out to main memory, and incur an average latency penalty of 84ns (we'll accept Sandra's reported value as representative for the purposes of this discussion).

While the mechanism for forward progress in the fabric relies upon ordering rules at the physical layer to give responses higher priority, the degree to which prioritization results in lower average latency or jitter for a particular flow is specific to the actual implementation.

Average latency is the sum of immediate latency measured Y times every X seconds divided by Y. Average latency is used to estimate size of the buffer, mainly because it does not change so often.
