Hey Andrew!   
      
    AL> I'm assuming the physical RAM size is actually 32GiB   
      
   ----- ":read !free --si -h" starts   
                 total        used        free      shared  buff/cache   available   
   Mem:            32G        110M         32G        778K         25M         32G   
   Swap:            0B          0B          0B   
   ----- ":read !free --si -h" ends   
      
   I believe that is 'better' output.   
      
    AL> with the system eating some amount of it for use as video RAM,   
    AL> BIOS shadowing, etc.   
      
   Also it was/is a snapshot while the system is more or less idling.  Also,   
   also, I used to load small development systems in 2G ramdisks so that would   
   also have an impact on the above numbers.   
      
    AL> In any case, it appears you have plenty available.   
      
   Definetly overkill.  I can easily live with far less.  I think the optimal   
   would be 8G and even that is overkill on most days.  There have been times   
   where 8G is ideal.   
      
   However if I were running a number of virtual development systems   
   simultaneously I could see me wanting/using 32G without trying too hard.  So   
   far that hasn't been an issue.   
      
   Life is good,
