Long Waiting Time For Display

[DSobolewski]

Hello dev and member. Sorry for my bad english.

The following short script that displays the columns in different colors:

 

<?php
$starttime = microtime(true);
$now = gmdate("D, d M Y H:i:s") . ' GMT';
header ('Date: '.$now);
header ('Expires: '.$now);
header ('Last-Modified: '.$now);
header ('Pragma: no-cache');
header ('Cache-Control: no-store, no-cache, max-age=0, must-revalidate');

include('../libFC/FusionCharts_Gen.php');

$FC = new FusionCharts('ScrollColumn2D',800,400);
$FC->setSWFPath('../libFC/Charts/');
$FC->setInitParam('debugMode',false);
$FC->setParamDelimiter('

);

$tab_alpha = array(100, 90, 80, 70, 60, 50, 40);
$tab_kolory = array();
for ($cr = 0; $cr < 256; $cr += 51) {
for ($cg = 0; $cg < 256; $cg += 51) {
   	for ($cb = 0; $cb < 256; $cb += 51) {
       	$tab_kolory[] = strtoupper( sprintf( '%02s%02s%02s', dechex($cr), dechex($cg), dechex($cb) ) );
   	}
}
}

	$tablica = $tab_kolory;
	$cyfra = 1000;
	$ilosc = count($tablica);

   	for ($ia = 0; $ia < $ilosc_alpha; $ia++) {
       	$na = $cyfra + ($ia * $cyfra);
       	for ($ic = 0; $ic < $ilosc; $ic++) {
           	$FC->addCategory($na + $ic);
       	}
   	}

   	for ($ia = 0; $ia < $ilosc_alpha; $ia++) {
       	$na = $cyfra + ($ia * $cyfra);
       	for ($ic = 0; $ic < $ilosc; $ic++) {
           	$FC->addChartData(72.34,'label='.($na + $ic).'$toolText=Kolor: '.$tablica[$ic].' Alpha: '.$tab_alpha[$ia].'$color='.$tablica[$ic].'$alpha='.$tab_alpha[$ ia].'

);
       	}
   	}

$FC->renderChart(true);

$stoptime = microtime(true);
$total=round($stoptime-$starttime,5);
echo 'Time: '.$total.' sec';
?>

php script execution time: 0.15661 sec - good

 

Problem: time display in the browser: 11 sec !!!!! and browser it's blocked 5 sec.

 

The screen stays white and does not show up any words such as "rendering continues". It could use a progress bar.

How to overcome the problem of long waiting times so you see the chart?

 

Computer CoreDuo 2.66, 4GB RAM, Windows7, IE or FF (browser).

 

Best Regards

Hi,

 

By any chance are you using HTTPS?

 

Could you plese check once with Firebug Net tab in multiple test beds and let us know the figures?

No - only http. Link: http://wase.pl/testcolor.php

Testing on several different computers give similar results.

Hi,

 

Could you please try once setting animation='0' and useRoundEdges='0' ?

[DSobolewski]

UseRoundEdges is my primary parameter used.

http://wase.pl/testcolor2.php : defaultAnimation = 0; useRoudEdges = 0

http://wase.pl/testcolor1.php : defaultAnimation = 0; useRoudEdges = 1

Hi,

 

Please note that in order to render the chart timely, you would need to disable or keep the minimum required attributed related to alpha, tooltip, shadow and styles on the chart.

 

Hope this helps.
