hi,
which package you perfer?
mod_php on apache is okay but some people said fastcgi version of php
is faster, is it true?
thanks...

Depends. (That's the standard answer for ambiguous questions which don't
have sufficient technical details to provide an informed opinion).
Specifically, it depends on the environment (hardware and software)
you're running on. OS and version? Hardware platform--CPU, memory,
disk? Shared web server or dedicated? What sort of web application are
you running? How much traffic is it expected to handle currently? In 6
months? 1 year? 3 years?
It's my understanding that fastcgi forks a process for each connection,
running in the context of web server. mod_php runs as a thread, allowingfor
it to run concurrently with other processes on multi-CPU systems.

It doesn't matter. The difference in speed between the two approaches is
dwarfed by the improvements you can get in caching and improving your
algorithms. Further, unless you intend for your web site to serve hundreds
of hits per second, the difference won't be noticeable.
Don't start micro-optimizing until you know that the simplest approach
doesn't meet the specs.

Not quite. If it creates a process per connection then it wouldn't be
fast. FastCGI works sort of like a Java app server. It runs it a
separate process and communicates with the web server across a socket
connection. Since interprocess communication is very fast, FastCGI is
at least on-par with an in-process module in terms of performace. And
the decoupling of web-server from the app-server allows resources to be
better managed, so it could be actually be faster. For example,
persistent connections when used with mod_php is quite wasteful, since
every Apache process would own a connection to the database, even
though it might actually spend majority of the time serving image files.

in fact, security is also one of the concern. people said fastcgi
version is more secure, and reliable

For security on my shared web host, I use CGI when I need to run a perl
script as a specific user. My ISP provides CGIwrap for this purpose.
Otherwise, I run all my site using mod_php. It can access the MySQL
database and display the pages and is fast enough.
Since you have a dual core system, I'd use mod_php. You'd be able to benefit
from it immediately with a threaded Apache server. And the site will
scale if you add more CPUs.

Theorectically, except PHP isn't thread safe, and requires you use the
pre-fork model of apache. This is suppose to change, eventually. Word
is mod_php is faster, by and large though, probably because its
integrated more with apache than a completely seperate cgi process. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I noticed that with Slackware they don't include

So is this just a Slackware mishap or is there
a good reason to no longer permit PHP from

Hello
I'm interested in hearing reflections by seasoned web app
developpers about the different ways to write PHP apps, and especially
how they compare in terms of performance, whether it's the PHP part or
connections to MySQL.
As far as I know, there are different ways to write a PHP application:
- CGI, ie. the usual way : some PHP code in web pages, and the PHP
interpreter is loaded each time a PHP page is called

If I switched from mod_php to fast-cgi, would I need to make any

How many of you are running Fast CGI instead of the popular mod_php?
I planning to change to fast cgi since my applications need around
15MB memory to handle a single request, so consider if Apache running
in multi-process mode, serving 300 clients, then it nearly used up all
my memory in my server.
Any experience can share how to handle large concurrent clients for
PHP?

Correct me if I'm wrong, but isn't running PHP via mod_php faster than
running it via CGI? If so, why would a web hosting company be running

following response:
"We run our php based on what is secure, not what could be a few
