That is a sweet cache hit percentage Manel (:

I agree, APC is the first step.

Great article Tom.

I have apache + mod_php + apc. I will try the configuration of apache + fastCGI + php.

I have APC installed from more than 2 years ago, and I only can recommend this to people that not use it. I think that really the first step is use APC.

I got a snapshot of the apc after running our website for a day and a half, just to share another “real world” example of what you can gain with APC. You can take a look at APC graphic.

I use also APC like “memcache”, to store global data that can be accessed between requests.

Just my two cents.

Tom,

gave this a crack on the weekend to great success, recompiling PHP 5.3.2 without the need for the Apache apxs headers for mod_php also reduced the compile time and final php-cgi binary size to boot.

For those playing at home, worked out you don’t need to use the “–enable-fastcgi” compile flags anymore, seems that got phased out with version 5 of PHP. Simply removing the “–with-apxs2″ compile flag (for mod_php) gives you the (Fast)CGI binary, plus the CLI binary if required.

Brandon, thank you very much for bringing hard stats into the picture. One thing your article doesn’t explicitly measure is the impact of migrating PHP out of Apache on the server’s ability to deliver static content at the same time it is delivering PHP content. I would love to see a benchmark in which static content is also being retrieved at the same time. Apache + FastCGI + APC should beat the daylights out of Apache + mod_php + APC in that scenario, which is of course the real world scenario. Your benchmark seems to beat up only on PHP, so it makes sense that mod_php + Apache and FastCGI + Apache are comparable in that situation.

(Of course one could also expect good results with an nginx front end serving the static stuff and proxying the PHP stuff to Apache + mod_php + APC. Just another way of reaching the same goal)

Hi Tom,

Thanks for the awesome article. I had a true forehead slapping, can’t believe I didn’t think of that, moment when I read the section about setting MaxClients on Apache.

Cheers,

Fletch

Great article, definitely going to examine some of our apps with this in mind!

On a related note, we’re seeing a weird issue with APC on one of our machines at the moment, with Apache’s error_log filling up with:

[Thu Mar 18 08:31:36 2010] [apc-warning] apc failed to locate local_config.php – bailing

This is happening every minute or so, does anyone know what is likely to be causing it?

Tom, thanks for the excellent setup guide for FCGI with Apache. Going to have to give this a shot on a VirtualBox Ubuntu image with a fresh PHP source compile…. hopefully can then push this live. Grand plan is to move to lighthttpd , but this is a nice ’smaller step’ to begin with…
