There no performance benefit to be gained that way. The speedups occur 
if you go from php-cgi to mod_fastcgi+php-fcgi.

That's indeed the case. PHP does the accept() loop for you. It's 
tailored towards making the fcgi environment as invisible as possible to 
the script.

php-fcgi is also rumored to do the heavy initialisation part for your; 
at least that's what I infer from rumors that it caches compiled code 
from one invocation of a script to the next.

Summing it up, I'd try a comparison that spits out a few lines of actual 
HTML (the more, the more realistic), and measure the times not only for 
a single run but for (say) a dozen runs.

It would be interesting to read your findings here.
