Hi there,

We are having a massive problem with incredibly slow user logins on our site.

After clicking the login button it can take anything up to a minute for a user to be sent to our homepage. The frustrating thing is that if after clicking login you then immediately use the navigation you are taken to the chosen page and you are logged in.

I have used Fiddler (http://www.fiddler2.com) to track the HTTP requests and it is showing “home.aspx” as a page request almost immediately after clicking login, yet the home page only loads 30-60 seconds later.

What could be causing this delay between the request and the render?

We are running DNN Community Edition 05.04.01 (26) .

Any help is greatly appreciated.

Thanks,
Donovan

Please revisit the recycle options of your IIS application pool.

Speed up your DNN Websites with TurboDNN

Update: After speaking to our hosting company this morning they are saying that DNN was hitting the server memory limit (500mb) and therefore resetting the application pool. This would make sense to me as it would explain why the site runs perfectly for about 10 minutes and then is slow before running well again, all down to the site having to reload into the application pool after each reset.

They seem to feel that increasing the memory to 1000mb it will solve the problem but my concern is that we may have a memory leak somewhere and it will simply use the 1000mb as it has used up the 500mb... we obviously can’t keep throwing memory at the server.

Does anyone have any idea on how much memory DNN needs, or uses, typically? How can I find out how much memory my current installation is using? Is there a setting in host that can be adjusted to monitor/maintain DNN’s memory usage?

Thanks,
Donovan
