Hi all, I have a brand new (well purchased a month ago, but it's the 2011 base model) that I'm running headless on my network. I am using screen sharing to connect to it from my 2012 MBA. Performance has always been a bit sketchy, but it's now gotten worse. It connects fine, but I am getting many instances where the (mini's) screen is black, or parts of it are black, and that clears when I drag a window around. It is also incredibly laggy. I'm getting by, but it's becoming very close to being unusable. I was wondering if RAM might be a factor? It only has 2GB. Even connected directly to a thunderbolt display it seems really slow, but that might just be me comparing it to the air! Also, this happens when both the mini and the air are hard wired running through an airport extreme. Any ideas?
