Como hice las pruebas:

1.- Reinicie la maquina.
2.- Inicie apache
3.- Corri el test y guarde los resultados.
4.- Reinicie la maquina
5.- Inicie lighttpd
6.- Corri el test y guarde los resultados.

el archivo index.php solo ejecuta la funcion phpinfo();

Conclusion: Lighttpd es mas rapido que apache incluso sirviendo PHP.
