I have recently changed by website and it is really loading slowly :- dancemidisamples.com

here is a report http://www.webpagetest.org/result/120906_78_ANK/

As far as I can tell the is a issue with this section of code

<link rel="icon" href="http://www.dancemidisamples.com/skin/frontend/base/default /favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="http://www.dancemidisamples.com/skin/frontend/base/default/favicon.ico" type="image/x-icon" />
<script type="text/javascript">
//<![CDATA[
var urlSkinsite='http://www.dancemidisamples.com/skin/frontend/em0040/default/';
//]]>
</script>
<!--[if lt IE 7]>
<script type="text/javascript">
//<![CDATA[
var BLANK_URL = 'http://www.dancemidisamples.com/js/blank.html';
var BLANK_IMG = 'http://www.dancemidisamples.com/js/spacer.gif';
//]]>
</script>
<![endif]-->

Does anyone have any ideas, people have told me it my DNS but it has a 49ms response rate according to http://www.webpagetest.org/result/120906_78_ANK/1/details/cached/

We are hosted with rackspace so I dont see how it could be the server. Its a dedicated server not cloud hosted

  • Careful--the report you've provided says roughly 7 seconds are spent waiting for the first byte. –  Sep 06 '12 at 13:18
  • You also really need to learn about limiting the number of http requests. Look into Google Closure compiler or something similar. –  Sep 06 '12 at 13:18
  • I can't really troubleshoot that, but I had this great [blog post](http://www.codinghorror.com/blog/2011/06/performance-is-a-feature.html) bookmarked that might be relevant to your interests. – Aaron Copley Sep 06 '12 at 13:47

  • Log into your server and look at memory usage. Also look for swapping, which can kill performance in a major way. If this is true, increasing the memory on the system can be a huge help. See this for some other info: http://www.magentocommerce.com/wiki/groups/168/optimising_your_web_stack_performance_for_magento – mcauth Sep 06 '12 at 15:52
  • Like @TheBlackBenzKid said the script is doing nothing and the load report that you post shows that there is a really long wait between the initial request and the first byte sent by the server. I think that you might look into your server configuration... What about hardware? Which web server are you using? – Andrea Giardini Sep 06 '12 at 13:58
  • Have you open_basedir enabled ? If yes disable it. – profy Sep 07 '12 at 18:07
  • Your bigest performance hit is 7 seconds you spend on the server preparing the first page not the JavaScript – MichaelT Sep 06 '12 at 13:24

This is a problem with your webserver rather than your code, looking at the report you linked http://www.webpagetest.org/result/120906_78_ANK/

Your browser had to wait 6.302s before starting to load the page, you should be investigating the Start Render column as that is what is causing the majority of your slowdown.

This is probably because you have poor DNS resolution and a low powered (shared) server that cannot process the request particularly quickly.

You should also look at consolodating files and including your CSS all at once etc, your website loaded 76 files at a total of 1,139 KB

Though that doesn't explain the 6 seconds of loading before the page started, it does explain the 7s (13-6) wait while the browser loaded and rendered the content

Suggestions:

  • Look at getting a new web server (or increasing the power - ram/cpu), perhaps a VPS if you are using a shared host
  • Enable page caching (System -> Cache Management)
  • Research how to reduce the number of HTTP requests your website makes
  • Investigate your DNS resolution (using one of the many tools available online)

    @TheBlackBenzKid The comments on this answer were deleted by a moderator (ME, actually) because they were inflammatory, argumentative, and a razor's edge away from [Stack Exchange etiquette violations](http://serverfault.com/faq#etiquette). If you have an issue with this answer which you would like to raise in a comment you may do so, however please bear in mind our network-wide policy on civility.

The problem is your using Magento Commerce on a poor performing server. Magento is a highly tuned eCommerce script (terrible IMO for this and several reasons). I also see your on Rackspace; this is even more concerning. You need to post information about your setup, the whois records look corrupted too. It could also be caching and many other reasons.

This script:

<link rel="icon" href="http://www.dancemidisamples.com/skin/frontend/base/default /favicon.ico" type="image/x-icon" />
<link rel="shortcut icon" href="http://www.dancemidisamples.com/skin/frontend/base/default/favicon.ico" type="image/x-icon" />

Is doing nothing to effect the site speed.

Speed up Magento

Why is Magento so slow?

I took a look at the site using Chrome's built-in Developer Tools (CTRL + SHIFT + I). The PageSpeed function lists numerous improvements that will speed your site up, but we are talking about milliseconds here.

Using the Network function (still in Developer Tools), we can see that all the many images, js & css files take small amounts of time, but even combined, they are dwarf by the initial time to return the page, which takes over 5 secs from my PC.

Digging down further, if I click on the html item, and go to the Timing tab, I can see that it takes 14ms to connect, 5s 'waiting' and 164ms to receive the code. Which suggests the problem lies with either your hosts nameservers or your web server.

enter image description here

I don't think it is DNS related as such; we all talk to different DNS server yet experience the same wait. Unless your TTL is very low (not - it appears to be @ 24hrs), forcing everybody to go back to your registrars nameservers, it suggest the nameservers at your host may be at fault. If not, then the problem probably lies with your web server.

I'm afraid I don't have the time (and probably the skills) to take you any further at this time - hope this helps.

I'll propose an answer that doesnt mean going in and rewriting all the dang SQL statements.

It's actually really easy:

  1. delete the line that adds the new items list to your homepage

  2. add these lines in its place

    New Items {{block type="catalog/product_widget_new" products_count="5" template="catalog/product/widget/new/content/new_list.phtml"}}</div>

  3. got to app/design/frontend/default/hellovieo/template/catalog/product/widget/new/content/

  4. edit new.phtml

  5. find and delete the following lines

    div class="widget-title"> h2>< ?php echo $this->__('New Products') ?>

Once you save this, you are done. My load times went from 10 seconds to less than 1 second.
