Hiya

While i am writing my website i am now hosting it myself, the php, database and everything using Wamp
http://www.wampserver.com/

( works nicely i must say )

anyway, is there any programs that i can run on my pc to test the site to get an idea of the speed my php scripts can run at, how many concurrent users will be able to view the same page without me hitting to big a bottleneck and so on?

Thanks for your help

Your best call is to run several tools:

1) Xdebug [ http://www.xdebug.org ]
This is a debugger and profiler for PHP. Once the profiler is enabled, it will save a file that contains many information telling how many times each functions have been called, and how much time they took to be ran.
You can use a program named wincachegrind [ http://sourceforge.net/projects/wincachegrind ] to analyze that trace.

Do this page after page, and you will see where are the bottlenecks in your code.
Most of the times, they are in the database related functions.
But too, this will let you know if a specific functions is called too many time. It could be good to optimize it.

2) To test the load, use something like apache's fundation jmeter [ http://jakarta.apache.org/jmeter/ ].
It will allow you to plot and simulate hundreds of concurernt connections, and how many time your server took to respond.
You can find a basic explaination about how to setup a web page test plan here: http://jakarta.apache.org/jmeter/use...test-plan.html

But take care to disable xdebug profiler, as the profiler slows down your scripts, or you will have thousands of trace files to clean up.

here is a web page test ploted result:



I don't know about wamp, but I know that xampp provide the xdebug extension by default.

Thanks for all that info
I do have to check it all over and over again because everything runs so fast when hosting it on your own pc but i'm sure when its on the web it will all fall apart hehe

I will have a look at Wamp for the xdebug extension although not seen anything of it yet.

I think the only real database bottlenecks my site will hit is if the roulette gets played by a few people at once as it does make a lot of calls to the database on each spin or bet placing.. and it makes calls to 3 different fields.
other than that the only real heavy thing on database is viewing profiles as all there details and guestbookin there, forums evidently makes a fair few calls but thats split into pages so not all at once.

codewise, i think 2 of my includes my slow things down a little, 1 being my smile finder and the other the cookie reader.

Thanks again for all the info
