Does anyone have some more detailed numbers about the performance improvements? <a href="https:&#x2F;&#x2F;debbugs.gnu.org&#x2F;cgi&#x2F;bugreport.cgi?bug=55676" rel="nofollow">https:&#x2F;&#x2F;debbugs.gnu.org&#x2F;cgi&#x2F;bugreport.cgi?bug=55676</a> says &quot;a few percent&quot; but I&#x27;m more curious with regards to what language constructs, and whether it&#x27;s mostly from the removal of recursion or the other &quot;closer attention to performance.&quot;
