  88                   process.  This is the best indicator of browser memory

  92                   <strong>Shared:</strong>
  93                   Resident memory size that is currently shared with 2 or more
  94                   processes.  Note: For browsers using multiple processes, if we
  95                   simply added the shared memory of each individual process,
  96                   this value would be inflated. Therefore, this value is
  97                   computed as an approximate value for shared memory in each of
  98                   the browser's processes. Note also that shared memory varies
  99                   depending on what other processes are running on the system,
 100                   and may be difficult to measure reproducibly.
