-<p>This section has been rewritten with the Log4j 2.6 release. The
-previous version only reported <em>service time</em> instead of <em>response
-time</em>. See the <a href="performance.html#responseTime" class="xref
page">response time</a> sidebar on the performance page on why this is too
optimistic.
-Furthermore, the previous version reported average latency, which does not
make sense
-since latency is not a normal distribution. Finally, the previous
-version of this section only reported the maximum latency of up to
-99.99% of the measurements, which does not tell you how bad the worst
-0.01% were. This is unfortunate because often the "outliers" are all
-that matter when it comes to response time. From this release, we will
-try to do better and report response time latency across the full range
-of percentages, including all the outliers. Our thanks to Gil Tene for
-his <a href="http://www.infoq.com/presentations/latency-response-time";>How NOT

-This hides the fact that a single spike in service time adds
-a queueing delay for many of the subsequent operations. Service time is
-easy to measure (and often looks good on paper) but is irrelevant for
-users since it omits the time spent waiting for service. For this reason,
