Page speed not good despite CDN and caching. Can this be fixed?

[devdg]

My page speed results are here, showing a speed of 40 seconds. I get an F for compress text, compress images and cache static content.How do I resolve this?

Also..

I've set up a CDN.  Is it a problem for SEO, that there is a copy of all my images and content at cdn.mysite.com? We get lots of search traffic through google images search.

I checked both your home page and an article with PageSpeed. The same issues I mentioned earlier still remain.

You offer a wedding photography site so it is natural you offer high-res images. Understand that even if you optimize your pages as much as possible, your site speed will always be noticeably slower then a webpage such as this Q&A section which is made up mostly of text.

With the above understood, Page Speed and other similar tools will ensure you maximize the speed for your site. You currently have dozens of images which do not specify an image size. For facebook, there are a dozen images which are 50x50. You can add one line of code to take care of those 12 images. There are still dozens of images left on your pages without image sizes specified.

I am not familiar with W3 Total Cache, but I can see in Page Speed dozens of images on your cdn without a cache expiration specified.

Another quick tip, if you are using PhotoShop, be sure to always use the "Save for Web & Devices" option which will compress your image files. Otherwise I highly recommend Yahoo's Smushit which is a free and fast online lossless compression tool. This would seem to be the #1 issue on your site presently and will make a noticeable difference in loading speed.

Thanks Ryan.

I've now added in a cache date on all images in W3 Total Cache.  I will also add in image height and with attributes for all images in my theme.  All the images in our posts already have those attributes. Hopefully the theme files will help.

I've installed w3 total cache a few weeks ago, but our site speed still seems incredibly slow for some people. It hasn't improved noticeably.

I've checked in "Page Speed" and the score is 82/100.

To improve your results you need to make the following changes:

• specify a cache date for your images of at least one week. Your images are showing up properly on your cdn but they still need a cache date for improved scores and results

• specify all your image dimensions. Your html for an image should look something like <img src="/images/mustang.jpg" width="200" height="100" alt="Mustang GT5.0" />

Try making those two changes and your speed and score should noticeably improve. I would recommend PageSpeed to check your speed in the future as it is an industry known tool. YSlow would be another great tool to use.

None at all
