Lighttpd fcgi and rails banchmarks

I have been testing various web development solutions on an unloaded
Mandrake Opteron 150/1Gb box.

I am a little confused about my results on lighttpd with apachebench.
Results are requests per second, all test scripts simply output ‘Hello,
World’ in plain text.

Static HTML 11488
FastCGI Perl 6350
C CGI 2015
Perl CGI 597
Ruby CGI 259
RoR FastCGI 180 <-- ??
RoR CGI 31 <-- !!

Does this look right, or should I be looking at problems with my config?
I expected Rails to have greater overhead since it is a full framework,
but
is this the best performance I can expect?

Were those figures taken with the app in development or production mode?
