SBCL is an amazing implementation and it has an amazing compiler. I would argue that it is one of the best compilers around. Javascript compilers in browsers are pretty impressive - but given the far fewer resources that SBCL development has had, SBCL is remarkable. It's a fast compiler that generates fast code. I would be using it (and do for some applications) if I didn't also need my own large C++ computational chemistry code written over decades.

yes sbcl is "only" a tiny impl. Makes me wonder how far franz or other can be .. you know how chez-scheme was leagues above the other implementations while nobody knew until it was open sourced

The smallness of SBCL helps speed its continued development. Compiling it from scratch on my laptop and running the smoke tests takes about 1 minute.
