Virtuemart Checklist for Speed

[kdmonk]

Hello I am new to Virtuemart but a fast learner. Before I start looking for information that will increase the speed of my site, is there a checklist available for such a thing?

So far,

• Site is installed a virtual dedicated server, IIS 7
• PHP5
• Latest version of Joomla as well as Virtuemart 2 latest version
• SEO Enabled hopefully
• What other things do I need in order to increase speed in the images as well as pages?
•

Hello,

You could use cache technics and also JCH optimize to combine and zip your CSS, icon combine sprites to one file and javascript files (http://extensions.joomla.org/extensions/core-enhancements/performance/site-performance/12088).

Keep in mind if you cache to exclude vm cart page & module from that caching (you will find several extensions, i use jotcache).

With JCE you may have issues, like broken js, you have to try it a lot!

Looks like your server can handle high loads, so I believe you should just optimise your content.
Use the right format for images - Jpg and png are prefferred, as they reduce the size of the image.
Combine images into css sprites
combine java into separate file
likewise, combine css
it's a good idea to add css to header and java to footer of the page, this way the content would be fast to render.
get rid of the unnecessary elements in your code.
