We recently migrated our database from SQL 2005 to SQL 2008 R2. Application is performing pretty fast and as expected. However when any queries are called from linked servers then it just hangs. Select top 5 * from linked server takes forever and when killed takes forever to roll back. This impacts the whole system big time. Suggestions?

What has changed except the SQL Server Engine version?
