do you experience issues with the database performance? did you check the DNN event viewer (in admin menu) for other related issues?

I see from the other posts that there are the same issues with speed that I am experiencing. I am also timing out like crazy on two new 5.5.1 site I just put up. I am using KeepAlive and can't believe all the non-responsive time out errors that I am receiving. Is there anyone who has found a setting or two that can be tweaked? I tried truncating the database and that doesn't help. Is thins just a 5.5.1 bug, or a memory hog issue? I am on a shared hosting provider that placed my sites in dedicated app pools and it is so expensive to add dedicated resources.  If it is a memory hog, what is the best previous release that doesn't have speed and time-out issues? Thanks!

Putting a DNN site on a dedicated pool ON SHARED HOSTING is slowing things down, because usually the memory size is not more than 32k (or less). Ask your hoster the pool size.

Have you changed the caching to Heavy ? Do you use disk or memory for paging ? Is the SQL server ok, because usually the timeouts come from the SQL. Not always but usually.

I have my hosting provider checking the database. Per your suggestion in another post, I also am having them check if the latest .NET security patch is applied to my webserver. Here are the other error types I see in the event viewer:

DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider

These two are related:

Is that Net 2 (3.5) or Net 4 ? The Scheduler errors are something i have seen also in ALL my DNN installations latety. So i have switched back to Net 2 (3.5) because i do suspect this is the cause. But the scheduler error can be put off, just go in the schedule options and make those to happen daily or something. Those errors alone can't timeout your whole DNN portal.

It's NET 2 (3.5). Thanks for that info Dimitris. I'll get rid of the scheduler.
