   Not really when compared to e.g. modern web browsers.  IIRC the rule   
   of thumb with ZFS is to have at least 1GB of RAM for each TB of   
   storage.  My old file/media server had 4.5TB of storage and 4GB of RAM   
   and worked fine.  The new one has 6TB of storage and 16GB of RAM.   
   (Thankfully purchased months ago before RAM prices skyrocketed.)

   My file/media server is effectively a dedicated "appliance" although   
   I built it myself instead of buying something off-the-shelf.  However,   
   I believe plenty of people use FreeBSD with ZFS as a general purpose   
   desktop/laptop system.

   No doubt because of the licensing issue that is the reason ZFS has to   
   be installed via dkms on Linux instead of being native.
