[FASTCGI] CGI vs FastCGI

I have to develop an C++ application that will be used on a web server
and to choose the most performant interface between CGI and FastCGI.
Therefore I've done a trivial performance test with an simple "hello
world" application to compare both interfaces.
I've made the test with this configuration :
* Intel Core 2 Duo E8400 @ 3.00Ghz
* 256Mb RAM
* Linux version 2.6.26-2-686 (Debian 2.6.26-15)
* lighttpd-1.4.19 (ssl)
* ApacheBench v2.3
The Lighttpd config is the default config and I've loaded mod_cgi and
mod_fastcgi. Only one process is running for FastCGI.
The results of the test (running on localhost) with 1000 requests and a
concurrency of 10 are :
* 5000 req/s with FastCGI module
* 100 req/s with CGI module.
Can I trust these results (big difference)? Has someone already done a
performance test between these two interfaces? And how were the results?
Thanks for your answers.
