I recently moved to a new server with Windows 2008, IIS7.5 and SQL Server 2008, the new server also has 24 CPUs against the previous 8 and 32GB Ram against 24. Since the move the site has seen response times drop from 3 to 5 seconds on average and in some cases on a page reading info from a stored procudre just to display it from 3 to 8 seconds.
I have run a response time checker it shows an increased WAIT time in a waterfall chart from 1 to 5.1 seconds.
I have tried as much as I can find, including changing pipelines, 32/64 bits app pool etc.
Any ideas welcome?
