There are several technical terms that are heavily used in performance engineering. It is important to understand these, as they form the cornerstone of the performance-related discussions. Collectively, these terms form a performance vocabulary. The performance is usually measured in terms of several parameters, where every parameter has roles to play—such parameters are a part of the vocabulary.
Latency is the time taken by an individual unit of work to complete the task. It does not imply successful completion of a task. Latency is not collective, it is linked to a particular task. If two similar jobs—
j2 took 3 ms and 5 ms respectively, their latencies would be treated as such. If
j2 were dissimilar ...
