To compare performance, we need a performance test suite.  Without
measuring the impact of these changes, we cannot rationally discuss
the alleged slowdown.  This has been discussed before, but AFAIK no
one is working on that.

Volunteers are welcome to work on such a performance test suite.  Once
available, we can make it mandatory for the results to be presented
when someone comes with a suggestion to move code from C to Lisp, or
vice versa.
