Rob,
thank you for your honest feedback; it looks like some work and attention is needed on 6 before it performs not worse than 5.5.1+
After quite some efforts and tweaking, including the use of .net 4, I manage to stay above page speed 80 in most cases and I would be scared of dropping below 60, for instance, just because of the upgrade..

You should only see a minor drop in PageSpeed scores for anonymous visitors, especially if you are using your own skins and menus etc. Logged in for editing is another matter entirely, but you can always replace parts of the interface and disable the popups etc. That's going to make this all quite usable again.

To be honest, I found 5.6.2 faster than  version 6,  I agree 6 is smoother and and really cool, but a resource killer.

My website is on a dedicated server with Celeron , Windows 2008 Standard R2 (64), MS Sql  2008 Express, with I GB Ram only, and it is fast.

I did some small improvements like removed loads of unused  CSS Classes, and optimized images.

you may test it here and appreciate if you may give me your comments.

That's what I'd call a very heavy site. Here are some notes...

  • You've got a score of 56-61, similar to a default DNN setup.
  • You should enable compression in DNN and/or IIS
  • Your article manager needs to be resampling images for display
  • Your html payload is relatively huge at 172Kb.. appears to be primarily caused by the magamenu
  • You've got a missing theme.css - 404 error
  • The CSS is fine.. you could put the container.css into the skin.css instead of loading both
  • The js is also fine.. DNN Corp just needs to merge a handful of the DNN js files to improve this for everyone
  • Homepage has a 1.14Mb payload
  • Repeats load nearly 200Kb each time - mainly because you have a big html file


Note that a site with lots of content and images can still have a high score.. it judges how it performs relative to the load.

My heaviest site is similar to this site but still scores between 85 and 92 on Page Speed, depending on which page I check. It requires less than half the hits and loads in about 300Kb, with only 35Kb loading on repeats.

If you fix up compression and get Packflash to thumbnail your images, then you'll improve the score. I don't think you can do much else though, because you won't want to lose the mega menu and all the little flags etc.
Regards
Rob
