Vlad has been doing some of the integration work to get TraceMonkey working on ARM.  He&#8217;s posted <a href="http://blog.vlad1.com/2008/09/11/tracemonkey-coming-to-a-pocket-near-you/">a first set of performance numbers</a> which are more or less in line with the x86 numbers that <a href="http://weblogs.mozillazine.org/roadmap/archives/2008/08/tracemonkey_javascript_lightsp.html">were originally posted.</a>  Here&#8217;s the graph we care about:

</a>
</div>
<p>
The ARM backend is about 2,000 lines of code and is still in earlyish stages &#8211; but it&#8217;s working.  It&#8217;s a great first step to bring fast JS perf to ARM-based mobile platforms.</p>
