See Univ. of Illinois Tech report UIUCDCS-R-88-1461 "A C++ Interpreter for
Scheme" (I believe this was presented on a C++ Conference) which
essentially describes a re-write of a subset scheme interpreter in C++.
The result, according to the authors, is a faster interpreter with
improved internal structure, increased modularity and decreased effort to
maintain and extend it. The paper contains a detailed comparison of
performance. Take it for what it is worth.
