<p class="MsoNormal">I think terminology that reinforces that the baseline (unloaded) latency is not always what users experience, and that latency under load is not referring to some unusual corner-case situation, is good. So, I like “idle latency” and “working
latency”.<o:p></o:p></p>

<p class="MsoNormal" style="margin-left:.5in">I’ve found that idle is a good descriptor for unloaded metrics, and for semi-technical audiences ‘working’ is a very good term. But for lay people, the term ‘loaded’ seems to work better, especially since we are
talking about a metric that relates to capacity.<o:p></o:p></p>
