Are there big systems written in JS?

All Mozilla products.

I don't think anybody can seriously think that Javascript performance can ever beat what CMUCL/SBCL can do to Lisp code that is declared through and doesn't use CLOS (plus assorted other techniques). And even if so, if a certain somebody would finish the LLVM backend for SBCL then it's easy picking :-)
