Levelling both at same time = twice as fast. Give or take a few hours /played in the far end.

Until lvl 20 levelling is far too easy to be worth dualboxing, but after that when some mobs are actually half a challenge you should try google to find one of the many great free guides out there to get an idea of where you can get quests. If you're just farming mobs or doing "get 10 snout"-type quests your only advantage is that you're less likely to die, but on the "kill 20 skeletons" you'll be doing them twice as fast thus slightly boosting your exp/hour, and in either case you can multiply that with 2 (seeing as you're doing 2 chars).
