I'm on the last El Capitan. Actually I have to restart the Finder every few days because the network drives either disappear or are no longer reachable. Sometimes the shortcuts disappear as well especially the ones that are located on a network drive (I tried both smb and afp). I've also noticed a lot of slowness throughout the OS. The spinning colored wheel shows up very often compared to previous OS versions and on all kind of actions.
