Are your setting MAXDOP to 1 or is SQL Server configured that way?

Anthony - I did not use MAXDOP in my query.
I am executing same query in another server it is showing Parallelism .
Why would you assume the queries would be the same? In fact the same query on the same server could have different execution plans with different data.
So why don't you tell us what is the real problem? Do you think the lack of performance of the query is due to the fact that parallelism is/ is not showing up in the execution plan?

Anthony, I have restore the same database in the two servers and executed the same Query.
I want to how to set the Parallelism. Does Parallelism slow down the SQL performance ?

SQL Server Express 2012 Parallelism settings:
Cost Threshold for Parallelism=5
max degree of parallelism =0
Machine has 4 cores and 8 logical processors
