    Strange ...I was just looking into the setting and i had found these

    LogicalCPUs on Prod is 32

    LogicalCPUs on Dev is 40

    MAX DOP Setting on Prod is 8

    MAX DOP setting on Dev is 16

    And yet you had just told me the settings were identical on both boxes. :blink:

    Also note that simply having a more powerful machine is cause for query plan differences even with every, and I mean EVERY OTHER SINGLE THING identical between the boxes/sql server/databases/etc.

    And now we know the reason I don't answer these types of questions. 😛 The answer is always "something is different... go figure it out". 😉

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
