Performance
Performance is either the subject of programmer performance (speed and quality of programming) or program performance (speed and quality of execution (or of compilation when the program under consideration is a compiler)).

Programmer Performance

Papers about various studies comparing programmer/language performance:

In summary, the experiences tend to show that with lisp you get faster development times, at least as fast execution times, and less variance amongst developers (so there's less risk in using lisp than other programming languages).

See benchmark for programs trying to measure the performance of Lisp systems.

In the "program quality" aspect of things:

and numerous other pitfalls in programs written in "normal" programming languages.

That should give a lot of reasons to use CL.
