Galaxy Core Prime Lollipop update question

Hi,
I have recently discovered that a Lollipop update has become available on the Galaxy Core Prime, my device, through a software called Odin as well as Kies. It's a manual update that I would definitely like, but my question is, for a low end device like the Core Prime, will Lollipop slow my phone down or take up too much space?
Thank you for any help.
