Category results slow, but Latest products fast

[cleancut]

Hi,

Our site runs on a 10 core server with 12 gb memory. Its fast enough to power a VM store with 1200 products.

PROBLEM:
The site takes about 5-6 seconds to load a category result with 20 products (when pagination is set higher it takes even longer...)

COMPARE:
But when clicking the core module 'latest products' it loads 60 products in only 2 seconds.

SOLUTION?
Why is my VM so incredibly slow and does anybody have an idea as to why?

Thanks for looking guys,

Hi,
Please give more info :
-Vm & Joomla revision.
- plugins in use.
- active modules.
- Template framework.
Only with correct settings, your site with 1200 products, have to display 20 product in 1 second max(with 2 cores and 4gb memory).

1: do a test with Joomla default template.
2: do a test in a category, not using custom plugins, related categories and products.
3: activate Joomla debug mode, and check your queries and memory in use.

When i see this in your HTML header, i have half of answer:

Try to optimise your loading script and CSS, i won 3 secondes in a customer site only on minify and group the css and javascripts !

check your pagespeed here : https://developers.google.com/speed/pagespeed/insights/?url=http%3A%2F%2Fwww.cleancut.se%2Fbutik%2Fknivserier%2Fglobal-2-serier%2Fglobal
I was thinking i cannot find a site having a page speed < 40, but your have 36/100. It is very bad, mean your site is not optimised and the problem is not only Virtuemart or Joomla!

thanks alot for looking.

Joomla! 3.3.6 Stable
VirtueMart 3.0.3

Modules are all core modules + DJ-MediaTools Album (which is probably not to blame since all non-product pages are loading fast)

Plugins are all core plugins.

Will definately look at code structure. Thanks for the tip!

Joomla & VirtueMart versions are well out of date and insecure.    http://forum.virtuemart.net/index.php?topic=118683.0

Current would be J3.4.3 and VM3.0.9.4

Hi jenkill,
The full site have to be optimise, update.
VirtueMart 3.0.3 is the first problem but not only(server settings, CSS, image size ...)

[jenkinhill]

Yes, bad case of template bloat, too many products on a page and maybe a badly optimised server. But waste of time fixing the speed only to find the site gets hacked  ;-)
