Hi,
Last week we upgraded our system
Sql server 2005 to Sql server 2008
Windows 2003 to Windows 2008
32 cpu 64 gb ram to 64 cpu 256 gb ram
One server strcuture to Microsoft cluster
But our system is running slowly. Sometimes (random times) our queries are so much slow such as 10-20 times then older time.
When i connect to sql server as domain user it takes (the login time) about 8-9 seconds.
As sql server user (SA) the login times takes less then 1 second.
Our sql server service is running now as domain user. Is it possible that the reason for slowing is running service as domain user?
