Please tell us more, Chandra, even though I know nothing about Windows vs Firebird, I know that a detailed and specific problem description is more likely to result in good answers than general questions. You say that you migrate to Windows server 2012, what do you migrate from? Is everything except the server identical on the fast and slow server - e.g. indexes and plans for all problematic queries? The same number of users and the same content in the databases? What about database statistics? If there are specific queries running slow, you could post them here together with the generated plans and some information about the fields in the indexes being used.
