Server load with PHP as module (mod_php) and PHP with FastCGI (mod_fcgid)

Sat, 05/24/2008 - 00:20 — Alex

mod_php or PHP via mod_fcgid? Apachelounge.com shows that PHP with FastCGI is in 1.5 times better then PHP as module.

Fri, Sat, Sun - Fast CGI; Mon, Tue, Wed, Thu - PHP module; Fri - Fast CGI again.

UPD: Just to be clear: it does not mean that you should throw away your perfectly configured Linux box if you have Apache with mod_php. It means that on some hardware, some PHP applications, may work better with FastCGI, and if you want to find what is better you should experiment like apachelounge guys did and do not fully rely on "scientific" tests.

I think it would have been a good idea to have mentioned that these stats were gathered from Apache running on Windows Server, and not on Linux.

There's also no mention of any reliability. My tests of PHP/FastCGI on Linux (which I'll publish later this week) show failures that just don't happen with mod_php. I'd be very interested to see how reliable this combination is on Windows.

Wow, that has got to be the

Wow, that has got to be the most un-scientific test I have seen in a while.

Lets see:

1. Only Windows tested
2. eAccelerator used (certainly used to leak memory)
3. No configuration details given
4. No performance figures given

Its like just showing a graph and saying it concludes that Windows is faster than Linux without saying what its faster at.

What about performance?

I found the fastcgi sapi for PHP to be a bottleneck when I tested it. It has been a couple of years. How well does that server scale with fastcgi? I can deal with more load if the server responds faster.
