the proof here is to show up with a pure lisp grep
that is fast as the C
version. ... 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].
