Hi

I've only got 1 portal and approximately 300 tabs. Almost every tab has a single module on it.  Each tab takes 45 seconds or more to load. I put a trace on the DB and for each tab click there's approximately 1800 queries being sent to the DB. The queries seem to repeat themselves as follows (this is from the trace):

SELECT * FROM dbo.vw_TabPermissions TP WHERE  PortalID = @PortalID OR (PortalId IS NULL AND @PortalID IS NULL)
exec dbo.GetTabPermissionsByPortal @PortalID=0
exec sp_reset_connection

I'm running DNN 4.08.02

The more tabs I've added, the worse the problem has become.

Any suggestions greatly appreciated.

Wow. What a difference caching makes. I didn`t even know there was a setting for this. Tks Sebastian. You`re a lifesaver.
