33<p>Nulgrind is the simplest possible Valgrind tool.  It performs no
34instrumentation or analysis of a program, just runs it normally.  It is
35mainly of use for Valgrind's developers for debugging and regression
36testing.</p>
37<p>Nonetheless you can run programs with Nulgrind.  They will run
38roughly 5 times more slowly than normal, for no useful effect.  Note
39that you need to use the option <code class="option">--tool=none</code> to run
40Nulgrind (ie. not <code class="option">--tool=nulgrind</code>).</p>
