Very well put! I'm just getting accustomed to this factor 3:-). A factor from 1 upto 2 is due to the compiler backend. And there is another slowing down due to goodies like dynamic typing and GC, so that we probably have to accept this factor 3 for large applications. Of course, if using the write-Lisp-really-fast style one can easily get an even larger gap to the "equivalent" C/C++ program. Nicolas.
