You can attack just as fast using only one hand as you can by alternating. But if you're dual wielding, there are perks that increase attack speed, which still apply even if you're only swinging one weapon (so if you want to save your weapon enchantment charge for certain enemies, you can just swing your offhand unenchanted weapon for everything else). Late in the game though I found myself relying entirely upon power attacks, which I'm pretty sure are also faster once you've taken the dual wield attack speed boosting perk.
