    Poor Performance on Xeon CPU

    Ron Pitts

      I've noticed some poor performance when using Tableau Desktop with CPU Xeon E5-2640 against say Intel Core i5 for example, same physical memory.

       

      I would have expected the Xeon to beat an Intel Core i5 chip.

       

      If the tableau engine process is changed to use only 1 CPU (Set Affinity) then I get better performance on the Xeon chip than the default "All Processors" however the Intel core chip still wins.

       

      Any reason for this? 

       

      Even tried with/without hyper threading, same result.
