I am having a severe performance problem with a new install of DNN 5.5.01. on my localhost.  I’m sure I have something configured wrong. I get delays of 2-3 minutes when loading pages. I get a message in the browser “waiting for localhost”. This occurs almost always if I edit content, or save content. Eventually the page comes up, but it has often lost the formatting of its skin. I have no modules installed except Advanced Control Panel. 
I scoured the forums for slow performance issues, and made the changes suggested to no avail. Here’s my configuration:
Win 7 Enterprise, SQL Server 2008, IIS 7.5. 
I did a manual install as well as a MS Web Platform install (this is the current install) with same results. 
Host settings –
 Page Stage Persistance: Page
Module Cache Provider – Memory
Compression – gZIP
I have no exceptions or errors in the event log, nor I am getting errors in the windows App Event Viewer:
My guess is a problem in the IIS/SQL user account, but I really have no clue. Any ideas?
Thanks –

Thanks for the reply. No - I'm seeing no spikes while the site is waiting for localhost. CPU usage 1 - 4%, Physical memory 45%.
The app pool is set at Integrated, .Net 4, Identity =ApplicationPoolIdentity. I'm running 64bit, and enable 32Bit applications is false. Load User Profiles = false. 
I am running default app pool, which is where the platform installer put this. It is the only app in this instance of IIS. 

Baffling!

Thanks
Jack

PS: please check the scheduler jobs, there might be one running twice the same time...
