I've never seen a lisp program that out performed a well > written C program. Your exact phrase (which my response was in reply to) was "lisp and performance is not a thing". You didn't say 'LISP is not just as fast as C' - a different thing entirely. I disagreed with your original statement, which seems to mean 'LISP doesn't perform well'. Quite a few people spent quite a lot of time making LISP compiler output fast, to the point that it was possible to say "this compiler is also intended to compete with the S-1 Pascal and FORTRAN compilers for quality of compiled numeric code" [Brooks,Gabriel and Steele, 1982] and "with the development of the S-1 Lisp compiler, it once again became feasible to implement Lisp in Lisp and to expect similar performance to the best hand-tuned, assembly-language-based Lisp systems" [Steele and Gabriel, 1993].
