A Store Speed Optimization in Progress

Recommended Posts

Hi!

I have a serious issue:)

 

I did read alot of the great tips/posts here and trying optimize the speed of the site constantly for more than a week now, I reduce the webbsite download time a bit..but it is still very slow

 

We want to release the site soon, but first I need to enhance the speed...so this is making me crazy:)

I have installed the KISS debugging, so you will se that result on the screen at my site www.stylingagenten.se

 

When I put up the site at http://analyze.websiteoptimization.com I got this result: (As you see it has serious download problems)

 

Object type Size (bytes) Download @ 56K (seconds) Download @ T1 (seconds)

HTML: 11798 2.75 0.46

HTML Images: 224562 52.55 8.99

CSS Images: 142594 46.22 18.56

Total Images: 367156 98.77 27.55

Javascript: 41608 9.09 1.02

CSS: 21358 4.86 0.71

Multimedia: 0 0.00 0.00

Other: 0 0.00 0.00

 

 

Do you have any clue why my site StylingAgenten.se is so slow? All the underpages are also slow...:(

 

I guess the size of the files above has a part of the problem I have not fins any way yet to reduce them thou...

 

I did follow some tips here and compremized the .js and .css files. I also use Gzip comression.

 

Please help me!

 

Best Regards

Andreas

One other thing that I dont understand is that my friend site www.beautysecrets.se, using OScommerce has regarding to http://analyze.websiteoptimization.com a larger amount of image files to download...but it takes much faster time. How is that even possible, is it because of the provider of the server hosting? I use a quite big provider and they say they have fast responstime to their servers.

 

Please help me with this..I dont know what to do :'(

I have checked your page with page speed in Firefox and you would benefit from adding this into .htaccess

Placing your snow javascript at the bottom of the page instead of the top would increase page load

Hi:)

I found another strange thing with the KISS debugging that is shown at my site. One example is in the site below:

 

http://www.stylingagenten.se/hair-styling-conditioner-c-1_15.html

 

There seems to be a lot of duplicated queries, do you know why?

 

Number: 58

Time: 0.0003 Seconds.

Query: select products_description, products_id from products_description where products_id = '146' and language_id = '1'

 

Number: 59

Time: 0.0003 Seconds.

Query: select products_description, products_id from products_description where products_id = '146' and language_id = '1'

 

I really hope you help me with this :)

 

Best Regards

Andreas

Replace the google tracker with the asynchronous version (replace XXXX with your number)

 

<script type="text/javascript">

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-1XXXXXXXX-X']);

_gaq.push(['_trackPageview']);

(function() {

var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;

ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);

})();

Hi Paul!

Thank you for informing me this. So it is only added a "1" before the key in the asynchronous version? I have the trackingcode installed in footer.php and in checkout_success.php, should I write that number in both files? I'm sorry for my dumb questions:)

 

Btw. do you have any good tip where I can read how to install Analytics correctly? I used an old addon before, but the last months it seems to measure completely wrong.. Thank you for your help!

Andreas

The 1 should not be there (my error)

<script type="text/javascript">

var _gaq = _gaq || [];

_gaq.push(['_setAccount', 'UA-XXXXXXXX-X']);

_gaq.push(['_trackPageview']);

(function() {

var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;

ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);

})();

</script>

 

This goes in footer.php. It does not need to go in any other file

stylesheet.css should be loaded before the xxxx.js files

 

try moving the banner rotator to the footer.php

 

<script type="text/javascript">

$(document).ready(function(){

bannerRotator('#bannerRotator', 500, 4000);

});

</script>

 

Loading javascript initialisation later in the document allows the page to appear on screen with the javascript loading in the background

The browser of the client is caching the stylesheet. Since it is a static file there is nothing to cache server side.

 

 

Just a thought. If I created a PHP file with the stylesheet information in, would that be parsed and load faster than a .css file? I am just considering this, as the PHP file is parsed server side.

Hi!

I see that I have quite many javascript in the head sections in general, I will try move them down in the end of the body instead and hopefully it will help also.

 

Most of teh addons above is created for MS2, are they still effective for RC2 version of OSCommerce as I use?

 

I hope you had a great new year celebration!!

 

Best Regards

Andreas

I use v2.3.1 and they are still relevant. Do a file compare to ensure that they have not been previously altered. ( I have enable/disable categories and had to alter to suit)

Do you use like this http://www.csscompressor.com/ ?


:blink:
osCommerce based shop owner with minimal design and focused on background works. When the less is more.

Hi!

I did most of the tips from you and others here in the forum, I have enhanced my speed with approx. 20%. Thannx for your tips! It is still quite slow, and I found one thing that confuse me a lot.. :huh: that may be a step to the right way. If I compare the page speed with my site, see picture at link

http://www.stylingagenten.se/images/teststyling.jpg

 

with my friend site (he does not host the site himself), see picture at link

http://www.stylingagenten.se/images/testbeauty.jpg

 

My site has has a great download time and size 73,44KB for the first file (as it say) "www.stylingagenten.se"

 

My friend site has a much lower size (28,88KB) for his first file "www.beautysecrets.se"

 

But if you for example look at the total download time and sizes for all the files that is downloaded at www.beautysecrets.se, it has a much greater total size. Also when I check the web page size at some other tools it only measure the first file (73,44KB / 28,88KB)

 

I think my friends site seems much quicker because of that file is much smaller. What is that file, my index.php file is below 30KB how come does it says it is 73,44KB? Does it count procedures in the HEAD tags or something, but not in BODY or do you have any idea how it can differ this much and what I can do to reduce the size?

 

Thankfull for all help! :)

Hi!

I see at http://analyze.websiteoptimization.com/ the html size of my page www.stylingagenten.se is only 11,8K, see picture here:

http://www.stylingagenten.se/images/analyzstyling.jpg

 

and the html size of www.beautysecrets.se is 28K (as the page size mentioned earlier??), see picture here:

http://www.stylingagenten.se/images/analyzbeauty.jpg

 

This make me even more confuse how www.stylingagenten.se seems to have a much greater size as I described in the post above :huh: :) .....

 

Have a great evening/night

The images highlighted in red are either not there or an incorrect path is showing

 

Hi,

It is strange that is say it is missing, because that picture is shown in the browser. I found one thing that makes the picture seems slow. Its very slow when you click in the menu and hit for example this url:

http://www.stylingagenten.se/hr-styling-c-1.html

 

From what you see it in this picture:

http://www.stylingagenten.se/images/test.jpg

 

There are a lot of "red-missing" pictures, but they are actually existing. It is all the category/product pictures.

 

As you see in the picture they are all beginning download after each picture is done, this takes a long total time. That makes it slow in total. Anyone knows how this is possible to change?

 

Best regards :)

You have h1 and h2 tags in the head section which should not be there.

 

The 2 images do not exist

    * http://www.stylingagenten.se/images/line_x.gif

You could create a link to your jquery like this instead of serving it. (People will probably already have this cached so a faster load time, plus parallel downloading)

<script type="text/javascript" src="<?php echo (isset($_SERVER['HTTPS']) && (strtolower($_SERVER['HTTPS']) == 'on') ? 'https://' : 'http://') . 'ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js'; ?>"></script>
<script type="text/javascript" src="<?php echo (isset($_SERVER['HTTPS']) && (strtolower($_SERVER['HTTPS']) == 'on') ? 'https://' : 'http://') . 'ajax.googleapis.com/ajax/libs/jqueryui/1.8.7/jquery-ui.min.js'; ?>"></script>
