Re: huge performance diff between windows and linux.

Title: Signature
I just tested PHP 5.5.3 running on Apache as Fast CGI with mod_fcgid and got these results:

PHP version : 5.5.3
Platform : WINNT
--------------------------------------
test_math                 : 0.768 sec.
test_stringmanipulation   : 1.876 sec.
test_loops                : 0.728 sec.
test_ifelse               : 0.521 sec.
--------------------------------------
Total time:               : 3.893 sec.

And according to a wiki I read (don't remember which one) mod_fastcgi is supposed to be even faster.

So I guess PHP runs faster as CGI than a module, which to me is weird.

Which leads me to my next question, how is that possible having in mind that as per php.net:

===========
Warning

A server deployed in CGI mode is open to several possible vulnerabilities. Please read our CGI security section to learn how to defend yourself from such attacks.
===========

I guess it's time to open a bug in PHP's bugzilla site.

Hey I have an issue and I ran out of ideas.
I have two virtual servers, one running debian with compiled php and one
running server 2008 with php non thread safe version.
Both have 5.5.3 version installed and both have almoust the same config and
modules, with opcache enabled. 

However I ran the benchmark script found online and I get this values:

Linux:

The question is am I missing something? can somebody with more experience
advise me what to setup on php or iis to improve this?
Not to mention that the windows server has double amount of ram and cpu.

I know I know I should blame Microsoft but even so I doubt THEY can do anything
in this setup. So I doing my best on my own, I would love to have Linux on that
box but it's not up to me.
