I started the calculation about 30 minutes ago and it is still going. Any way to speed this up?</P> Fri, 05 Dec 2025 14:04:08 GMT https://community.esri.com/t5/data-management-questions/what-is-the-best-way-to-do-a-mass-field-calculate/m-p/1670848#M45803 MDB_GIS 2025-12-05T14:04:08Z https://community.esri.com/t5/data-management-questions/what-is-the-best-way-to-do-a-mass-field-calculate/m-p/1672658#M45804 <P>Hello&nbsp;<a href="https://community.esri.com/t5/user/viewprofilepage/user-id/199986">@MDB_GIS</a>&nbsp;<BR />Here are a couple of things I would suggest</P><UL><LI>Run the calculation via the feature service, not the database.</LI><LI>Try to close the attribute table and disable layer drawing during this operation.
