-      TODO: <a href="https://golang.org/cl/139258">https://golang.org/cl/139258</a>: implement -benchtime=100x
+    The <a href="/cmd/go/#hdr-Testing_flags"><code>-benchtime</code></a> flag now supports setting an explicit iteration count instead of a time when the value ends with an "<code>x</code>". For example, <code>-benchtime=100x</code> runs the benchmark 100 times.
