Stress Test?

Tekka

I wondering, could anyone point in the right direction manual wise to find out how i measure construction time, cpu load, etc ? I working on some simple exercises to try and improve my style of coding and I want to know if I'm actually making things better or worse 🙂

There are a lot of things to take into concideration when deciding weather or not a script is "good, better or best".

If your object is to "time" the execution of your own scripts I guess you could use a microtime() -function (click on link to go to manual) to time the "gap" in time from start of your script to the "end" of the script using timestamp in microseconds.

Yeah I did some reading on that during my googles, apparently its not very accurate as it takes into consideration the users download speed as well, I'm more interested in writing most the efficient applications I can.

I haven't read this article very well yet, but maybee it can help you on the way ??

Article - PHP Builder.com

It at least has a class for timing script execution and a lot of comments and tips as well...

<?php
$data = shell_exec(uptime); 
$uptime = explode(' up ', $data); 
$uptime = explode(',', $uptime[1]); 
$uptime = $uptime[0]; 
$load_average = explode('load averages: ', $data); 
$load_average = $load_average[1];

echo "$data<br>"; 
echo "$uptime<br>"; 
echo "$load_average<br>"; 
print_r($data);
?>

tells uptime and the server load, its averages etc.

Thanks jayant but it doesn't really do what I need.

ya i know, but u can monitor cpu load averages over time, and make same number of requests to the script and see which works method the best.
