[ATV2] Slow nightly / monthly builds

Hey,

i am using XBMC on an ATV2 running iOS 4.4.4. It runs absolutely stable and plays everything i want to play. I tried the new nightly builds and they have nice new features, so installed them. But i have to say, that they are, compared to Eden, very slow. Menu is slow, scrolling is slow. Even playing vids is slow. On Eden i have absolutely no problems playing 1080p mkvs, but on the nightlys they are stuttering a lot.
i just wanted to post this, because i want to know, whether this is known or perhaps this is only my ATV2??

thanks a lot for this great piece of software!

That's what you get when install nightly builds, things could work smoothly or NOT, things could work right or NOT, that's why nightly are not recommended to use, except that you're ok with this warnings.
