Then, run the executable, which will write an <tt>mlmon.out</tt> file when it finishes. You can then run <tt>mlprof</tt> on the executable and the <tt>mlmon.out</tt> file to see the performance data. <p> Here are the three kinds of profiling that MLton supports. </p> <ul> <li> <p> <a href="ProfilingAllocation">ProfilingAllocation</a> </p> </li> <li> <p> <a href="ProfilingCounts">ProfilingCounts</a> </p> </li> <li> <p> <a href="ProfilingTime">ProfilingTime</a> </p> </li> </ul> <p> Going further </p> <ul> <li> <p> <a href="CallGraph">CallGraph</a>s to visualize profiling data. </p> </li> <li> <p> <a href="HowProfilingWorks">HowProfilingWorks</a> </p> </li> <li> <p> <a href="MLmon">MLmon</a> </p> </li> <li> <p> <a href="MLtonProfile">MLtonProfile</a> to selectively profile parts of your program. </p> </li> <li> <p> <a href="ProfilingTheStack">ProfilingTheStack</a> </p> </li> <li> <p> <a href="ShowProf">ShowProf</a> </p> </li> </ul> </div> <p> <hr> Last edited on 2007-07-08 20:58:34 by <span title="c-71-57-91-146.hsd1.il.comcast.net"><a href="MatthewFluet">MatthewFluet</a></span>. </body></html>
