Yes they will.  :-)

NDMP isn't "faster" or "slower", it's just different.  In many
situations it will be faster because you can avoid some bottlenecks, but
it depends on how you set things up.  NDMP can write directly to a tape,
go over networks, through other machines, etc.

Network appliance filers will prefer to schedule user data service over
NDMP service.  So if you have a filer that's running low on horsepower
(but still very zippy with serving data), you can find that NDMP jobs
crawl.  

But most of the time the same things that make NDMP slow make other
backups slow (lots of tiny files, overloaded networks)
