Hi all,

Hopefully this isn't a dupe post - I did a search and read through a ton of posts but didn't see anything, so here goes. I am attempting to set up DNN v4.3.5 as a corporate intranet site. I have the site loaded and running ok, but I am bogged down with speed issues something fierce. It is wholly unusable to me in the present form, and I'm out of ideas.

The machine that it's running on is Server 2003 Enterprise, with 4 Xeon CPUs running 3.4Ghz & 4 Gb of ram. It's a *fast* machine. I currently have IIS and SQL Server Enterprise on it... nothing else. By all logical accounts, this sucker should haul. It doesn't. 

Now, I've taken steps to improve this following previous posts I've seen. I turned on compression in IIS6, installed PageBlaster, I'm using the default low-bandwidth DNN-Gray skin, I made sure it's running it its own 2.0 AppPool. None of this seems to be making a difference. I had AD authentication on but disabled it because I thought it might be the cause of the delay. No luck there. I've even removed and reinitialized the database once to no avail.

Since we have a great deal of content already, I'm wrapping a lot of this in iFrames. Is there a known issue with iFrames? The server dishing out those pages is a similar machine, only running IIS and serving static pages. 

Help!

Thanks,
Shane

Shane,

Don't know if this information will help you or not. The reason I found your post is because I am having DNN speed issues as well. Frankly, your post is the most informative one I have found so far - and you are looking for solutions too!

I'm building something simular for our company intranet. I'm using iframes as well. I'm using them to expose Word, Excel, and PDF, files users have already built.

I'm using forms security. AD and integrated authentication had problems I didn't have time to resolve.

It made a big speed difference using virtual directories in IIS and wiring them to the iframes. I didn't use the authenticated user's credentials. (uncheck the box on the Security Credentials page in the wizard) I used a specific user name.

This delivers the folder listing in http rather than through NTLM. It's really fast and works well over the WAN.

Hope that helps.

If you can resolve the load issues with DNN, let me know. All I can find out is that this is a common problem. I have yet to find a solution.

The best performance I've gotten out of DNN is when our SQL server had problems. Pages delivered up VERY fast, but the login module would not display. Reboot server solved problem, but speed issue came back.
