How long should Dissolve take?

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?

For future reference... since I presume that you found out via the help that it can take a long time and there are some suggestions in the help to speed things up
