I vaguely remember seeing some notes in the past saying that there was a bug in many earlier versions of FreeNAS, which resulted in an artificially high reported ARC hit ratio, and that this bug had been fixed (somewhere in the 9.10 series, perhaps?). Didn't pay much attention, which is probably obvious by how little detail I remember about this.
Then I took a look at the ARC stats for my server the other day, and I'm kind of surprised. I'm using my server at home, mostly SMB/CIFS file sharing, some AFP, a few NFS shares to a Ubuntu VM on another machine. I do have Plex running in a jail, along with the so-called "pirate suite" (Transmission/SABNZBd+/CouchPotato/Sonarr). The server has 128 GB of RAM, and a reported ARC size of about 80 GB right now. Hit rate is 34%:
Am I right in thinking that's kind of low? Or is that the new normal?
