    Do you have a link to the article, please?  Our standard is as follows:
    ·          For servers that have NUMA configured, MAXDOP should not exceed the number of CPUs that are assigned to each NUMA node.
    ·          For servers that have hyperthreading enabled, the MAXDOP value should not exceed the number of physical processors.
    ·          For servers that have NUMA configured and hyperthreading enabled, the MAXDOP value should not exceed number of physical processors per NUMA node.

    I would recommend you increase your cost threshold for parallelism to something between 30 and 50.  The default of 5 is from a long time ago and based on very different hardware from what is available now

    The NUMA config is left to its default as I checked ..
