Use FreeData property to keep your CalcCache size limited - ObjectVision/GeoDMS GitHub Wiki

FreeData property

By default, calculation results are not stored persistently in the CalcCache. The default value for the FreeData property is true.

By configuring the FreeData property to false, calculation results, if they meet all other conditions, are stored persistently in the CalcCache. If the property is configured for an item it applies to this item and all it's subitems.

In general it is advised to store only results that are time consuming to recalculate and that are re-used in the same of in new sessions. This keeps your CalcCache size limited and results might be available faster, as less disk I/O is needed. It requests some experience on which expressions are time-consuming to calculate.
