question: lollipop quick circle apps topic

I was curious, do those in other countries who have received the lollipop update from their carrier have access to quick Circle case functions on their android lollipop device? Also, I have used a few lollipop roms on my LG g3 such as validus, liquid smooth, cm 12 and have noticed that the validus rom is much slower to boot then the others. I'm not complaining at all, I'm just curious why some ROMs boot faster than others?
