pallelism

  • I have a series of crystal reports, executing stored procedures against a 4-processor machine, in sql server standard edition.

    I have turned on parallelism, to use 3 of the 4 processors, at a minimum threshold of 8, but cannot get any of these reports to use more than 1 of the processors.

    Is there something I can do or something I should look at to determine if and when parallism is being used?  How about something to influence parallelism?

     

  • Do you have a high minimum query plan threshold for determining what queries recieve parallelism?

    Also, have you restarted the server (or at least SQL) since you made the change?

  • The default setting was 5, however, I bumped it to 8, without noticing any change.  

    Both Sql Server and the physical machine have been rebooted.  Again without much change.

     

  • SQL Server creates and executes a parallel plan for a query only when the estimated cost to execute a serial plan for the same query is higher than the value set in cost threshold for parallelism. You need to decrease it instead of increasing it.
