I'm using USU5 pro, and it works for me.... strange...

I have usu5 pro caching enabled

I will have another go, when I got some more spare time. I use KISSMT as well with caching. As a side note, I have changed all $HTTP_xx_VARS to their $_xx versions throughout my site

I have done the alterations to product_info.php. When completing the alteration to the top of the file everything is ok. The error occurs when I complete the alteration above require DIR_WS_INCLUDES . 'template_bottom.php';

This is the error that occurs

Edit: It is producing a cache file in the tree directory

Maybe updating it can resolve the issue. Also if your using gzip option inside oscommerce instead of gzip pages with .htaccess file can generate the problem on some environments.

[acidvertigo]

On my github network page there are my changes to the oscommerce code.

I'm tryng to remove the deprecated $HTTP_XXX_VARS code and applyng some php tricks to increase performance.

You can follow changes here https://github.com/acidvertigo/oscommerce2/network

Turning off the gzip compression in osCommerce solves the problem

Hi acidvertigo!


Great Work!


The $_GET supergobals not need to decode in some place, so much be faster. (IE in header.php)

From PHP manual:

Quote

Note:

The GET variables are passed through urldecode().

Thank you for the tip!

[acidvertigo]

I tried other little changes on functions/general.php and functions/html_output.php changing the function tep_not_null in isset. Seems a little bit faster but i don't know if isset return the same bool results of the tep_not_null functions. Anyone can help?

Hi,

Has somebody any experriencies in gzip? I think all web browsers support HTTP gzip at 2011.


I can reach Page Speed Score from 62/100 to 91/100 with some features.
css and js files gzip downloads



I add *.css and *.js files to *.css.php and *.js.php and rewrite template_top.php csss and js links

insert the top of the new php files
for *css.php

<?php
ob_start ("ob_gzhandler");
header("Content-type: text/css; charset: UTF-8");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 7;
$ExpStr = "Expires: " .
gmdate("D, d M Y H:i:s",
time() + $offset) . " GMT";
header($ExpStr);
?>

for *css.php

<?php
ob_start ("ob_gzhandler");
header("Content-type: text/css; charset: UTF-8");
header("Cache-Control: must-revalidate");
$offset = 60 * 60 * 24 * 7;
$ExpStr = "Expires: " .
gmdate("D, d M Y H:i:s",
time() + $offset) . " GMT";
header($ExpStr);
?>

My main files for v2.3.1:

Quote

catalog/ext/j...2.custom.min.js (74%%).
catalog/ext/j...8.12.custom.css (81%%).
catalog/ext/j...ry-1.5.1.min.js (62%%).
catalog/ext/j...x-1.3.4.pack.js tömörítése (64%%).
catalog/stylesheet.css (77%%).
catalog/ext/j...cybox-1.3.4.css (79%%).
catalog/ext/9.../960_24_col.css (79%%).
catalog/ext/j...lery.1.1.min.js (66%%).
catalog/ext/j...atepicker-hu.js (45%%).

Perhaps this new files can be gziped static and after include them before the last ?> close tag. In this case not need ob_start. I think this feature can do in a new contribution.

You can do this putting this code in .htaccess file of your root directory:

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

[acidvertigo]

Oppss correct code is:

SetOutputFilter DEFLATE

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript

A very long thread. I wish someone can make a resume

[Yak39]

Hello all, I am feeling sorry to bloat even more this topic with my request.
I went thru some of the mods suggested here, from category enhancements to the various tep_get queries.
I also tweaked the .htaccess file adding deflating and duration timings.

Fact is that I am still getting no clue on where my OSC is running slow. The firs load of the catalog takes 23 secs! Specifically the queries that look like are getting things slow are again the categories query and the header_tags query.

I run a quite heavily modified shop including STS (disabling didn't give any performance improvement).
Can someone please help me understand where the problem lies?

Seems something wrong with your hosting company and not with the script

You can check here the speed of your site: http://tools.pingdom.com/?url=www.schermaontc.com/ecom&treeview=0&column=objectID&order=1&type=0&save=true

The first time response is very long, then the site loads faster.

Check your apache configuration
