 Below the paging statistics is a column of lines regarding the virtual

+The first few lines describe,
+in units (except as noted below)

 pages copied on write (`cow'),
 pages zero filled on demand (`zfod'),
-pages optimize zero filled on demand (`ozfod'),
-the ratio ozfod / zfod as a percentage (`%ozfod'),

+pages reactivated from the free list (`react'),
+the average number of
+times per second that the page daemon was awakened (`pdwak'),
+pages analyzed by the page daemon (`pdpgs'),

 At the bottom of this column is a line showing the
 amount of virtual memory, in kilobytes, mapped into the buffer cache (`buf').
