Performance Problems In Multi-Page Content Items

Performance Problems In Multi-Page Content Items was created by Oleksiy Shevchukevych

Hi Guys,

It took me a while to figure out that Simple Image Gallery PRO creates performance problems when I use it in multipage content item.

I have content item splitted up into 17 pages. Each page contains 2 galleries and every gallery consists of just one image. The total number of such-one page galleries is 35. Given such a setup I'm having 2 problems:

1) It takes extremely long to access any of content item's subpage (around 14 seconds)

2) When I access any of content item's subpage using IE, web site's template just drops

You can access multi-page content item I'm having problems with using this URL:

www.boxingcoachmike.com/index.php?option=com_content&task=view&id=8&Itemid=10000

If I remove all galleries from this multi-page content item everything works just fine.

Thanks
Cheetah

Please switch popup engine to e.g. Slimbox and check again. Lytebox -the one you use- uses php output buffering which might be "heavy" on your server. Let me know...

I've tried every popup engine. Problems still exist.

OK, try this. Open up the file mambots/content/plugin_jw_sigpro.php and at about line 284, replace this block of code:

				// create thumbnails
				if (file_exists($tempfolder.md5($_images_dir_.$name).$format) && filemtime ($tempfolder.md5($_images_dir_.$name).$format) + $cache_expire_time * 60 > time()) {
				 $html .= $leftcomment.'<img alt="'.$clickopen.'" title="'.$clickopen.'" src="'.$tempfolder.md5($_images_dir_.$name).$format.'" />'.$rightcomment;
				} else {
				 $fromname = $mosConfig_absolute_path.$rootfolder.$_images_dir_.'/'.$images[$a];
				 $toname = $mosConfig_absolute_path.$tempfolder.md5($_images_dir_.$name).".".$format;
				 $toname_live = $mosConfig_live_site.$tempfolder.md5($_images_dir_.$name).".".$format;
				 $result = makeThumb( $fromname, $toname, $image_type, $_quality_, $_width_final_, $_height_final_);
				 if($result)
				    $html .=$leftcomment.'<img alt="'.$clickopen.'" title="'.$clickopen.'" src="'.$toname_live.'" />'.$rightcomment;
				 else
				    $html .='<span>Error creating thumbnail!</span>';
				}

with this:

				// create thumbnails
				$toname = $mosConfig_absolute_path.$tempfolder.md5($_images_dir_.$name).".".$format;
				$toname_live = $mosConfig_live_site.$tempfolder.md5($_images_dir_.$name).".".$format; 
				
				if (file_exists($toname) && (filemtime ($toname) + $cache_expire_time * 60 > time())) {
					$html .= $leftcomment.'<img alt="'.$clickopen.'" title="'.$clickopen.'" src="'.$toname_live.'" />'.$rightcomment; 
				} else {
					$fromname = $mosConfig_absolute_path.$rootfolder.$_images_dir_.'/'.$images[$a];
					$result = makeThumb( $fromname, $toname, $image_type, $_quality_, $_width_final_, $_height_final_);
					if($result) {
					$html .= $leftcomment.'<img alt="'.$clickopen.'" title="'.$clickopen.'" src="'.$toname_live.'" />'.$rightcomment;
					} else {
					$html .= '<span>Error creating thumbnail!</span>';
					}
				}

Let me know...

Hi Fotis,

Thanks, it helped. Problem #1 is gone. Although problem #2 still exists. i.e. in IE template drops and I'm getting some javascript errors. In Firefox everything is fine.

Thanks

I've switched to Lytebox popup engine and I'm not getting JavaScript errors anymore. But template is still missing in IE.

Well, for one let me note that your servers is a bit slow on response. Now try this. Change this part in your template:

<!--[if lte IE 7]>
<link href="http://www.boxingcoachmike.com/templates/rt_sporticus_v2/css/template_ie7.css" rel="stylesheet" type="text/css" />
<![endif]-->
<!--[if lte IE 6]>
<link href="http://www.boxingcoachmike.com/templates/rt_sporticus_v2/css/template_ie.css" rel="stylesheet" type="text/css" />
<![endif]-->

with this:

<!--[if IE 7]>
<link href="http://www.boxingcoachmike.com/templates/rt_sporticus_v2/css/template_ie7.css" rel="stylesheet" type="text/css" />
<![endif]-->
<!--[if lte IE 6]>
<link href="http://www.boxingcoachmike.com/templates/rt_sporticus_v2/css/template_ie.css" rel="stylesheet" type="text/css" />
<![endif]-->

Perhaps the 2 stylesheets conflicted. Notice that the change is on the first "if" statement. Get back to me...

Changed the template. It still doesn't work.

As for slownes, I have noticed that it's slow only when first request is made after a while. Any subsequent request is much faster. Probably thubnails get regenerated that's why it's taking so long

What time have you set for the thumb cache in the plugin's parameters?
