Currently we have a Mac Mini (late 2012) Running El Capitan 10.11.6 (most current as of time of post), here are the specs: 2.3GHz intel 4 core i7 16GB 1600 MHz DDR3 1TB 5000 RPM boot drive (no files stored) Promis pegasus 2 r8 Raid 12TB usable (x2 one for time machine back up) Both pegasus are plugged into the first generation thunderbolt port (10GB) and the mac mini has apples server app (5.1.7 most current as of time of post) running only a file share. Currently there is only two people who use the file sharing, both of witch are using photoshop, adobe bridge, and illustrator (Creative Cloud - most up to date possible.) Our problem is that the server is slowing down big time. half the time i can't connect to the server via VNC, its refusing to print until I restart and the ram is cleared. The 16GB Ram is maxed out and using swap space. The CPU is idle at 94% the network card never goes over 20MB (have seen speeds of up to 115MB) I Have looked everywhere on the internet and i can't find any solutions other then upgrading the server to a Mac Pro and maxing the ram out with OWC after market RAM. Any suggestions would help.
