HOW IT WORKS
When a user visits your site, they are usually a guest, with no items in their basket, so the HTML for each is identical. Search engines like Google, Bing etc also see the same content
These days your website is ranked not only on content, but also on how quick it responds, so search engines take into account the speed of your page generation. The reasoning is that the poor quality sites tend to have slower servers as they're cheaper. This helps separate the good from the bad for the vast majority of sites on the web. However, not all slower sites are due to bad servers, it can be because the server is mis-configured or requires a lot of processing to generate content on a dynamic site
WHAT PERFORMANCE CAN I EXPECT
On my VPS, the home page as I write this is over 850 times quicker - This is the server side processing time to generate the page HTML. This is NOT going to affect CSS, images, JavaScript or any other files loaded by your browser when your browser starts generating content
To see the figures yourself take a look at the page cache bar that displays at the bottom of the screen on the site. This is only viewable to admin users logged in - Your customer's will never see this (though for the demo store this has been made public)
If you don't see the page cache, refresh the page to see the bar

THINGS TO NOTE
==============
Product pages viewed will only be updated with the view count when the original cache file is generated. After that, it will bypass the whole OC system, therefore no database calls to update the count is made. However, any analytics type software will be unaffected (and the stats will be more detailed too no doubt)
Dynamic modules, such as recently viewed won't work for non-logged in users, and if you have dynamic modules that generate content for non-logged in customers, it won't update. AJAX requests are unaffected by this
For those wishing to have live stock counts, please install the additional "ajax_stock.xml" vqmod supplied in the downloads list
FAQ
====
Q: Can I just delete cache files for a certain product?
A: Unfortunately, since products can be woven into different areas of the site, its pretty much impossible to do. As of version 1.2.0 you can delete an individual page's cache file if you're logged in as an admin
Q: Does this improve the google page speed tool values?
A: No, this mod increases HTML generation speed only
Q: Will this definitely speed up my page load time?
A: Nothing is guaranteed, however I've not had anyone with less than 100 times the speed of the original as of yet (and don't expect to)
Q: I turn my site to maintenance mode but it still shows the site. Why is this happening?
A: Due to database connections not being made, the script doesn't check for maintenance mode, and therefore can't display it. When using maintenance mode I highly recommend disabling the cache mod
Q: Does it work with a mobile/normal version correctly?
A: Unfortunately as OC doesn't have a mobile structure built in, this can't be handled in a standard module. If you'd like to get in touch for a price to customise this please do
Q: How do I see the page cache bar in multistore
A: You will need to log in as an administrator, then select your store from the "Store Front" menu item on the right hand side of your dashboard screen
