Browsing Large Music Collection

I'm thinking of buying an Apple Tv, but my main concern is if it's tremendously slow to scroll through hundreds of artists?

I currently stream through my PS3 and it's very fast to scroll down the artist list, where as my friend's Roku Box takes forever and a day. Couldn't find any YouTube video's demostrating this, so I hope some one can enlighten me.

Thanks in advance:)
