[Bobs-devel] performance tester

[Rene R. <re...@gr...>]

Hi Joe. 
I've begun testing the performance of the database to see where it could
use some optimization.

These two functions make it easy.

Add a "var $time; to the class you want to test and the functions below.
It'll handle several names in one turn and add timings to display a
total. (good for loops inside loops)

I use it like this:

// start the timer
$this->timer("Array_merge", microtime(), "start");
// whatever you measure gets done here.
$result =  array_merge($result, $this->compare_data ($db_data, $array));
//stop the timer
$this->timer("Array_merge", microtime(), "stop");

// print the result
$this->get_times();

-------- functions ------ beware of line-wraps -------

// just a simple performance counter
function timer ( $name, $microtime , $type) {

	list($usec, $sec) = explode(" ",$microtime);
	$time = ((float)$usec + (float)$sec);
	if ( $type == "start" ) {
		$this->time["start"][$name] = $time;
	} else {
		$this->time["stop"][$name] = $time;
		// add the difference to total
		$this->time["total"][$name] = ($this->time["stop"][$name] -
$this->time["start"][$name]) +$this->time["total"][$name];
	}
	return;
}

function get_times () {
	$names = array_keys($this->time["total"]);
		foreach ( $names as $name ) {
		echo "Total time for $name was : " . $this->time["total"][$name] . "
seconds<br>";
	}
	return;
}
