    iqtedar (8/11/2010)


    i) if MAXDOP is zero - cost threshold value doesnt matter since sql engine will push the query to all the processsors right?

    No. The instance-wide MAXDOP setting sets...

    Sorry....

  • RE: MAXDOP - How many CPU's does it use

    Is it wrong to cry when someone tells me they don't know what Bulk-Logged is?

    BUSHY PLANS!! Thank you, Paul. Time to give that another read.
