Enable file compression and caching in .htaccess

Unload unneeded files. Combine and minify CSS/JS files. You can do it manually or using a plugin like JCH Optimize. Be careful because this can cause some JS issues. Test carefully.

Your site has a response time of 3.3s. Use Debug to see if anything is slowing down your site. If nothing is found, your hosting server is probably too slow.

Hi,
you have different problems :

Favicon is not found and checked 3 times. Use an online favion generator and add this in your template > index.php file in the header.

Your main php file is slow. Try to disable some module or plugin, to see why your mainpage need more then 2 seconds to load.
In some case when you have php errors and error log is active, this can slow down tour site too(in some case more then 1 seconds when you have many errors)

Minify and optimize your CSS,Images and javascript, but not only, some scripts are loaded 2 times, so i think some PHP is not well written and not check if javascript (and css) is already loaded.

I think on changing all this you can load your site in 2 seconds and not in 9 seconds as currently.

I like, all time we spend to answer, and at end the user changed nothing.

Always remind yourself, also other read the post :-) We could also write a sticky or add a page to docs.virtuemart.net

and I guess that even then some users would still ask about the same

Note: i had another warning for a site in the php error.log .
On correcting the file i won 2 seconds (from 4,1 to 2,2 seconds) and this was only 3 warnings !
I never seen before that this slowed so much a website.
