Streaming From Network Drive

I finally got a network drive mounted (I have to do it longhand from terminal currently) from my ATV. It’s a terrabite GRAID drive on a 100 base T hard wired network. But it’s SLOW. Even looking at the files (movies) list is very slow.

It’s unusable. Has anyone else tried this ?

PS My Macbook AIr attached to the same network via WiFi can stream from this network drive perfectly. Why is the aTV with a wired connection so slow ?
