<div class="paragraph"><p>With MLton and <span class="monospaced">mlprof</span>, you can profile your program to find out
bytes allocated, execution counts, or time spent in each function. To
profile you program, compile with <span class="monospaced">-profile <em>kind</em></span>, where <em>kind</em>
is one of <span class="monospaced">alloc</span>, <span class="monospaced">count</span>, or <span class="monospaced">time</span>. Then, run the executable,
which will write an <span class="monospaced">mlmon.out</span> file when it finishes. You can then
run <span class="monospaced">mlprof</span> on the executable and the <span class="monospaced">mlmon.out</span> file to see the
performance data.</p></div>
