i know its been discussed, i googled it, i searched it here but i didn't find an immediate answer to just a simple question. Is crossover faster for my intentions vs booting windows xp ?

I just want to run ie6 for cross browser testing and looking to have the fastest solution that does not take up a ton of ram. If crossover eats up as much ram and cpu as parallels i might as well go with that since it has my entire xp os on it, thoughts?

Spare me any flaming on this. thanks.
