.DESCRIPTION
  Configure Windows pagefile. Typically on windows server.
  On dedicated local drive.

  The page file size formula should be:
    (Max value of Committed Bytes + additional 20% buffer to accommodate any workload bursts)-RAM size
  For example: If the server has 24 GB RAM and the maximum of Committed Bytes is 26 GB, 
  then the recommended page file will be: (26*1.2)-24)  = 7.2 GB
