Hi I have DNN 5.0.0 and my admin site is slow; besides we created a news module that creates a page per news (I know... doesn't seem right but yes we did) now we have around five thousand pages and the performance decreased plus when updating a page through our module it takes a lot of time or gives the following errors:

The connection to the server was reset while the page was loading.
or
Null Pointer exception

The lines that give that errore on my code are:


                category = NewsContext.NewsCategory.FirstOrDefault(c => c.NewsCategoryID == categoryID);
                category.TabsReference.Load();

                parentID = category.Tabs.TabID;

If I retry two or three times more everything works fine.

Any ideas?
