nginx with PHP - windows performance

[jack_]

After 2 days of testing I'm able to run nginx on Windows Vista x64 SP2
with PHP
I'm using a Kevin Worthington 1.04 cygwin build with 2 worker processes
and 5 child's of php-cgi.exe
On a hardware like Laptop with Intel Core2Duo P8400 2.26GHz with 3GB of
RAM and 250GB 7200 1/min HDD
I've been able to receive results like below:

nginx + PHP
[Tested locally with Apache Benche - using: ab.exe -n 5000 -c 1000
127.0.0.1/
The file reached is index.php with code only <?php phpinfo(); ?>]

nginx + php 5.3.6 x86 build thread-safe -> 199 requests / sec
nginx + php 5.3.6 x86 build NON thread-safe -> 208 requests / sec
nginx + php 5.3.6 x64 build thread-safe -> 176 requests / sec
nginx + php 5.3.6 x64 build NON thread-safe -> 185 requests / sec

nginx + HTML
[Tested locally with Apache Benche - using: ab.exe -n 5000 -c 1000
127.0.0.1/
The file reached is index.html created by Kevin Worthington]

nginx with multi_accept off -> 445 requests / sec
nginx with multi_accept on -> 900 requests / sec

Level of failed requests never was higher than 5 requests.

        #

        #    deny  all;
        #}
    }
}



Any proposition for improvement ???
Enabling multi_accept on; with PHP pages is crashing connection.
