This doesn't have to do with OS X as much as it does my ISP (Comcast 15Mbps/3Mbps Down/Up). Comcast states you get speeds "Up to" those advertised which basically means you will never get those speeds but once in a blue moon it could happen. I've been watching my Router activity for a few minutes (see Top graph of the attached image) and I never get near either of those advertised speeds as expected. I am downloading Xcode DMG from Apple and a few torrents are running with no bandwidth restrictions. My question is currently I'm getting about 50% of my advertised bandwidth, if I reduced down to the 1.5 Mbps Comcast package would I probably still only get 50% of that bandwidth? I think I already know the answer but was curious what you guys thought.
