Is there a way of controlling the file size of my DNN 05.03.00 site? I've read the other threads that talk about the compression settings, and one of the was about a year old thread that talked about the compression settings in IIS, but according to Godaddy, I don't have access to that since I have the shared hosting.

 The problem is that when I add images and text or other content, the file size goes way up. ie, 8 to 10 pics, 1 <iframe> and about three paragraphs of text is close to 70kb and dramatically slows the page load speed and if I understand correctly, Google don't like that either.

 I found in my Host site settings where if offers different compression settings. Would any of these help?

     Thanks, Jeff...

Images (jpeg, gif, png) are usually internally compressed, if you need to decrease page size, you may optimize the files prior to uploading. HTML code size can be reduced by turning on compression in Host settings, I suggest using "gzip" for best results, make sure to leave whitespace filter unchecked!! Compression of static elements like CSS and JS files can only be switched on on server level or using a 3rd party solution like pageblaster from www.snapsis.com.

In my experience with the sites we build and host locally, one of the most significant causes of site bloat is the uploading / use of non-resized images. While some modules have the ability to auto-resize, the core editor / image gallery does not. What this results in for us is that users will just upload their images at full-size (say, 2000px wide for a digital photo) and then just resize it through the image properties. This causes the pages to render VERY slowly, and over time the image browser becomes nearly impossible to use (had one site with ~100megs of unresized digital photos that all loaded when you went to "Browse Sever"). I really wish there were a core solution to this as we still have to constantly 'educate' the site editors / owners of the value of resizing their images and even then they still do it.

However, I'd also reccomend the use of a module like Snapsis' PageBlaster to help you reduce page load and assist with compression if your problems aren't all image-related.

The pics I am working with are 200x200. I will say that I have not done anything to them yet to optimize them yet, so i guess I'll be addressing that next. I did do the gzip that Sebastian recommended and that did seem to help some. It cut about 15 kb off the file size as far as I can tell. I'm still working on it, so keep the suggestions coming. I'm listening to each and every one and applying them. Thanks for the help. Jeff...

Yeah, 200x200 images shouldn't cause that much of a problem, even with out them being optimized I can image they couldn't take up that much space... the problem I was describing would only apply if you were dealing with several hundered or so in the root portal directory (or really, any directory you navigate to).  Given, most my experience is front-end development (skins, design, structure, etc.) - however maybe the shared hosting doesn't allocate enough resources for the database / app pool to let the site perform at "full speed", however this is a completely random and wild guess... I've never worked in a shared hosting environ so I'm pretty much grasping at straws.
