measuring processing time

[mghfaust]

Hi,
Is there a way to

1. measure how much processing time a particular PHP web page forces on the PHP and/or database engine?

2. assess that measure? that is, what's considered light? what would cause a crash if 1000 people logged on in an hour? etc.

My site is getting pretty complicated, and I would like to know how much streamlining it's going to need before I make it live for the non-profit org I'm designing it for.

Hi

I got this from some where else, can't remmeber where but works for me at (http://www.thevoids.co.uk/)

<?php
$timeparts = explode(" ",microtime());
$starttime = $timeparts[1].substr($timeparts[0],1);

$timeparts = explode(" ",microtime());
$endtime = $timeparts[1].substr($timeparts[0],1);	  

echo bcsub($endtime,$starttime,6)
?>

It calculates the processing time.

Dont know if thats what you are looking for though

Thanks thevoids,
I see -- this script makes 2 timestamps: one at the beginning and one at the end of the script, and then calculates the time difference. That's simple enough that I should have thought of it.

Next though, I need to find out what constitutes 'fast'.

Any notion? Anyone?

$timeparts = explode(" ",microtime());
$endtime = $timeparts[1].substr($timeparts[0],1);

echo bcsub($endtime,$starttime,6)

I noticed from my own site using that "0.000080" is fast! 😉
