We have migrated our company database from SQL Server 2000 to SQL Server 2012 (big jump!). We haven't gone live yet on 2012. Something is wrong in our setup of 2012 because queries that run in 5 seconds on 2000 are taking 10 minutes or more on 2012. We restarted the 2012 server and checked memory before we run any queries. Memory looks good. Then we run a big query and memory usage starts climbing about 1 GB every 10 seconds. We kill the stored procedure, but memory usage stays high. We finally have to kill the entire SQL Server process to re-claim the memory.
Can you suggest where we might look for a solution to this problem? (I'm not a DBA, just a developer)
