    As previously suggested, have you looked into "parameter sniffing"? Google it.

    Also, are there any settings differences between the two servers like "auto statistics", etc. Last but not least, is one server using something like a SAN while the other is using it's own disks?

    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.
