I have the lowest tier Mac Mini 2012, and it runs OS X server. Currently I have configured: VPN, Websites, Caching, File Sharing, FTP, Time Machine, Open Directory, and run Plex Media Server and uTorrent web access. Would those proccesses all together slow down the computer that much? When I look at activity monitor, they take up basically nothing, the CPU usage is never over 20% when not in use (like games, etc.), plenty of free RAM, etc. yet the computer runs VERY slow a lot of the time. Does running all those server proccesses slow down the computer, or is it another issue that I have to figure out?
