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