Sarge etc carry 2.x, so if you're making a new install you may as well 
start with 2.x and be comfortable that the upgrade will go as smoothly 
as possible. That's really the main reason.

I don't know enough to say if it's worth upgrading an existing install, 
but it would seem an odd choice to make a new install with an old 
version when a more up-to-date version was availible from a reputable 
source like backports.org.

In my particular case, postfix 2.x has a few extra checks and controls 
I'm finding useful that are not in 1.x . Not a big deal, really, but handy.

As for performance - I really don't know. I haven't had any problems at 
all, and the POST's mail system gets a lot of very, very large messages. 
On the other hand, we don't actually transfer that many messages per 
day, so I don't think we'd be putting any detectable stress on postfix - 
especially not on the 1.5GHz Athlon it's running on.
