fault/s
   Number of page faults (major + minor) made by the system per second
   (post  2.5  kernels  only). This is not a count of page faults that generate
   I/O, because some page faults can be resolved without I/O.

majflt/s
   Number of major faults the system has made per second, those which
   have required loading a memory page from disk (post 2.5 kernels only).
