+<p class="Pp">The <code class="Nm">sched_ule</code> scheduler provides a number
+ of advanced scheduler features not present in
+ <a class="Xr">sched_4bsd(4)</a>, the traditional system scheduler. These
+ features address SMP and interactivity and include:</p>
+<p class="Pp"></p>
+<ul class="Bl-bullet Bd-indent Bl-compact">
+ <li>Thread CPU affinity.</li>
+ <li>CPU topology awareness, including for hyper-threading.</li>
+ <li>Per-CPU run queues.</li>
+ <li>Interactivity heuristics that detect interactive applications and
+ schedules them preferentially under high load.</li>
+</ul>
+<p class="Pp">The following sysctls are relevant to the operation of
+ <code class="Nm">sched_ule</code>:</p>
+<dl class="Bl-tag">
