    Running Windows 10 on two PC with MapInfo Pro 16

    Is there a way MapInfo Pro or Windows 10 can run better when doing some distance calculations using the Distance Calculator?

    I have noticed this often that Mapinfo does not use the full PC resources 

    PC running CPU 31% and Memory at 47%

    Go to the Backtage Area (the blue Pro tab to the left in the Ribbon UI).

    Under Options, in the System section, select Performance.

    This dialog lets you control two specific settings. The first is called Concurrency level, and this controls the number of cores that MapInfo may use. Make sure this is set to "Full" for highest performance.

    Thanks @Hakan Karlsson?  Is the concurrency level automatically set to 'full' out of the box? I saw mine was already on the full setting when I looked into the performance tab.

    Good question, Corey. I'm not sure about this. I would have thought we had set it a bit lower to not use all your resources.

    There is a similar thread on this topic here: https://li360.pitneybowes.com/s/question/0D580000048jc3I/support-for-multiple-processors?

    In this specific case, the Concurrency level has no effect on the performance. The Distance Calculator uses only one thread. And this specific case also seems to have the worst case scenario. Finding the nearest distance between a table of polygons to another table of polygons with hundred thousands of nodes.

    Typically the Spatial Index of a table speeds up these inspections but with huge polygons, the Spatial Index which typically is based on the MBR of the objects doesn't have a big effect.

    So, packing the table might help???

    Sorry, @John Ievers?, I had missed your question.

    No, I doubt packing the table will have any effect.

    Basically what would be needed is an improved spatial index where the individual segments of the big polygons get their own MBR. This would improve the performance radically.

    We have seen this in the Find Nearest stage in Spectrum Spatial where we introduced support for this specialised index type. You can read a bit more about it here: http://support.pb.com/help/spectrum/12.2/en/webhelp/Spatial/index.html#Spatial/source/Utilities/pgdbuilder/introduction.html

    PS: In case you were wondering, MapInfo Pro doesn't support the PGD Index
