+
+    <para>
+        In one of our previous releases (denzil), users noticed that booting
+        off of a live image and writing to disk was noticeably slower.
+        This included the boot itself, especially the first one, since first
+        boots tend to do a significant amount of writing due to certain
+        post-install scripts.
+    </para>
+
+    <para>
+        The problem (and solution) was discovered by using the Yocto tracing
+        tools, in this case 'perf stat', 'perf script', 'perf record'
+        and 'perf report'.
