I've been looking for days to see if someone has done a good, documented, PHP processing speed comparison between
and
Why I'm looking: The only test I saw are abount benchmarks, serving full pages or Hello, World -like test, without proper documentation on what exactly was tested. I don't care about the request/seconds, the hardware, but I do need to see what PHP script was tested and with what exact configuration.
Why these two: mod_php was known to be the fastest on processing PHP ( no static files, no request/response measuring, just processing the PHP itself ) but a lot has changed since then, including apache version. Nginx and PHP-FPM eats a lot less memory, so it'd be a good reason to change architecture but if they're not fast enough in this case, the change would be irrelevant.
I know if I'm unable to find one I have to do it myself but I can't believe no one has done a test like this so far :)
I have completed this test on CentOS 6.3 using nginx 1.2.7
, apache 2.4.3
and php 5.4.12
all compiled with no changes to default.
./configure
make && make install
With the exception of php where I enabled php-fpm
./configure --enable-fpm
All servers have 100% default config except as noted below. All testing was done on a test server, with no load and a reboot between tests. The server has a Intel(R) Xeon(R) CPU E3-1230, 1GB RAM and 2 x 60GB SSD in RAID 1. Tests were run using ab -n 50000 -c 500 http://127.0.0.1/test.php
Test PHP script:
<?php
$testing = 0;
for ($i = 0; $i < 1000; $i++) {
$testing++;
}
echo $testing;
I also had to enable php in nginx.conf
as it's not enabled by default.
location ~ \.php$ {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
include fastcgi_params;
}

I'll be more than happy to tune apache further, but it seems apache just can't keep up. The clear winner is nginx with php-fpm via socket.
