We have around 250 sites on our web server. We have a seperate server for our databases. I would say probably around 75% of these sites are dnn. For some reasons, our dnn sites seem to load slowly. The problem is, it's random. I have a custom program I wrote that sits on another server and loads all of our sites every 15 minutes to keep them cached. I've looked at the cpu usage on the server, and we hover around 30% of it's capacity so I think we are fine there. Our static sites load fine, and some custom applications we've built also load fine, it's just the dnn sites.
Now, I realize that the dnn sites are going to be somewhat slower because they are making a lot of requests for files, images, db tables, etc. but sometimes they might take a minute or longer to load.
If you click on these, chances are one of them will take a while to load to illustrate my point

Either through monitoring things on the server, or within dnn. Even a module that could help me with this? I'm not opposed to paying for one if it can help me identify and fix this.
