I started to Dissolve a moderately-large (~31,507 arcs) multi-attribute feature class some 20 hours ago. It's still running, entirely in memory (no file updates in the target geodatabase). How long should this take? When should I cancel processing because it will never complete? How might I speed up this processing?
