this is a follow-up to my post in another thread: doing most tasks, including tagging, searching, Combining tabbles, etc. uses ~450MB (as Andrea notes) on the SQL Express (2014) side with 1-3% CPU spikes and another 50-250MB for TABBLES itself, with 2-15% spiking CPU utilization.

This is with only TABBLES db running, although i run a parallel MSAccess db, linked to TABBLES db in SQLServer, that allows me to manipulate relationships and add other objects and properties to TABBLES.

once again with ~250 tags and maybe 20000 files
