Previously the server that I’ve been running a number of systems on has run 16GB, however, around the time that I also started leveraging Plex I noticed that the swap space has been consumed ever so slowly. I disabled some services that I no longer needed but still saw the swap getting eaten up and Plex is very much worth it.
So I’ve removed one of the 8GB memory sticks and installed a 16GB stick for a total of 24GB. That reminds me, I should probably replace my stripe with a RAIDZ array at some point.
