Trace Slowness
 

Is there a particular way to trace what plug-in(s) or scripts might be causing a slow down on my site? The server I have is superb and dedicated to me. I've optimized MySQL / Apache / PHP and not sure why the site loads pretty slow.

Not sure how accurate this is:

I've disabled 2 plugins, disabled Remote YUI (it was set to Yahoo) and cleared system cache, optimized database. Still loads slow. I'm using Chrome as well on a 20MBps cable connection.

I'm not an expert on this subject, but a couple things you can easily do: use Firefox and install the Firebug addon, then go to your page, open Firebug and go to the Net tab, then reload your page. This gives you a graph of everything the browser requests and how long it took.

Also, you can put the site in debug mode by editing your includes/config.php and finding the $config['Misc']['debug'] line, and changing it to true. or if you can't find it, insert this line (anywhere after the first line):


then when you load a page, at the bottom you'll see a line like:



and if you click on the (?) you'll go to a page that lists all database queries and how long they took. If you find one that took a very long time, you can probably figure out if it belongs to a plugin.

You should set debug back to "false" when you're done. Or if you want, there are ways to set it up so it's only in debug mode for you: www.vbulletin.org/forum/showthread.php?t=265999 , then you can leave it like that for as long as you want.

Thanks. This is the result.

That shows the template usage. You have to click on the (?) link (after "33") to get to the page with the queries.

Handy tool: http://webpagetest.org

This is Patrick Meenan of Google's tester. Many different, real world browsers, many different locations available.

I can already see why you have such a slow page loading times.

From this report here are some of the top issues that you can work on.

Thanks for the tools.

How do I rectify this when I disabled Yahoo Remote YUI?

http://yui.yahooapis.com/2.6.0/build...ntainer-min.js (66.1KiB)
http://yui.yahooapis.com/2.6.0/build/menu/menu-min.js (51.6KiB)

I'm not exactly sure of what you're asking with that last post but for the rest of the issues my guide can help you out, look in my sig.

Thanks. Took me forever to do this but did it.

Unfortunately I'm still at a D rating.

Still getting the sprites F rating? I installed / did that step too.

Also, when I enable Mod Rewrite Friendly URLs, my links no longer work at all. Clicking any link simply refreshes the home page.

Ah I just had a look at your site and it seems your running vbseo. Simply remove the friendly url rewrite in the htaccess and replace that part with vbseo's friendly rewrite rules.

Here is what I recommend you try, since it seems you're using vb 420 & vbseo.

If you have different friendly url rewrite rules than those listed below, then simply keep an editor open with them intact or save them to a document & replace the rules within #Friendly Rewrite Rules Start & #Friendly Rewrite Rules End

Would appreciate help on this. This is what I have in my htaccess

Hi, I can look it over for you. Here it is all fixed up for you. I noticed that you had some old caching rules thrown in there, I've taken the liberty to fix it up for you, copy this into your .htaccess & you should be set!


Also be aware that vbseo is known to contribute to very high server loads.. As far as server load goes that is as far as I can help you. However if you still want to try to finish off that pagespeed score then I recommend trying google page speed service. They require you to sign up... I got an email from them in a few seconds verifying my request.

I went from a score of around 80-82 up to 90-92 when I switched to them from using cloudflare.

Here are the settings I use with them. *If "use recommended settings" is ticked, that means that I didn't change any option.
For "Optimize Javascript", all 3 options are ticked.

The only problem with googles pagespeed service (when I used it) is that it really fekked up images making them very lossy and also the java scripts..food for thought.

Yes by default google does enable lossy compression. And in general it usually means a loss in quality when reducing the image. But lossless compression can reduce the file size without sacrificing any noticable image quality.

Also some mods aren't friendly when it comes to combining, deffering or compressing JS. I recommend playing around with the settings until you find out which works just right for because everytime you change the settings the pagespeed bot will recrawl your site, looking again for js resources and making the applied changes.
