I hope someone can address my problem. I have put a dotnuke website on a Windows 2003 IIS6 server (http://aonetweb1.aonet.it/)

The problem is that it works but it is extremely slow. It takes several seconds before loading any page.

Is there any way to speed it up?

Any suggestion is very welcome.

Regards

You will need to provide some more details on the site. Some questions that come to mind:

Is it hosted on a server with many other sites that would affect its responsiveness? Does the server and database have adequate resources (primarily memory and bandwidth)? Is there any bandwidth constraint set in IIS? Is there content on the site that could slow it down such as synschronous calls to other sites? Are you possibly running it with the debug switch enabled in web.config? Is caching enabled or disabled?

I agree with Paolo.  I'm new to DNN  and I'm not a programmer, but I would be happy to understand why this is happening...

It seems that every DNN install that I've made is slow on the first page laod ( even if the website does not have a big database).  I have DNN sites installed on different servers, but even if I installed one of them on a "superserver" with backbone bandwith ( and there are only 3 DNN websites installed on that server ), the home page is still loading slow ( 12 - 20 seconds ).

After the home page is loaded, everything goes smooth, for a while. If there are no visitors on the website, the next home page load will be slow again. 

Is it something somewhere that turns the website "to sleep" if it is not accessed for a while ( some kind of a timer )?  It seems that if I have some visitors on the website for a while (  I ment the website is accessed and has visitors ), the home page is loading much faster ( sometime even instantly ).  Somebody told me that he fixed this problem by seting up a ping to the website address every 15 minutes.

I would be very happy to know if there is a way to make the home page load faster, on a DNN website which has visitors occasionaly.  I am awared of the fact that this is a dynamic platform and it's pulling it's data from the DB, so it will take a while to load, depending on the amount of data which needs to be used on the forst load, but after I made some searches on the net I realised that there are DNN portals that are laoding instantly ( almost ).

Thanks a lot for your help....

Cybdig the issue you're describing is the .Net runtime. Basically for server performance reasons .Net shuts down applications that aren't accessed often. So the first time a page is requested and the application has to fire up all the DLLs must be loaded into memory again, this causes the slowness. If your site remains active the DLLs don't usually get unloaded, so they remain in memory and your site responds well to all requests.

Thanks Chris!

I had an ideea, but now that you explained me, I got it for good.

Is there a workaroud ( besides the permanent ping thingy - which seems to work though ), to keep the .dll's loaded in memory?

A trick to trick the trick?

Thanks again Chris
