For the vmstat sub-display:
vmstat.c: Move totfr to be under daefr and prcfr since it logically belongs there. Move all the count fields (wire, act, inact, cache and free) to near the bottom of the sub-display (after all the rate fields) to reduce competition with adjoining sub-displays. systat.1: Move things as above. Attempt to improve missing and poor wording in the description of the fields. The long sentence was hard to parse and didn't say anything about the different units. Increment .Dd.

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

memory system which list the average number of
|
||||
memory system.
|
||||
The first few lines describe,
|
||||
in units (except as noted below)
|
||||
of pages per second averaged over the sampling interval,
|
||||
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 optimally zero filled on demand (`ozfod'),
|
||||
the ratio of the (average) ozfod / zfod as a percentage (`%ozfod'),
|

pages freed by the page daemon (`daefr'),
|
||||
pages freed by exiting processes (`prcfr'),
|
||||
total pages freed (`totfr'),
|
||||
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'),
|
||||
and
|
||||
in-transit blocking page faults (`intrn').
|
||||
Note that the units are special for `%ozfod' and `pdwak'.

The next few lines describe,
|

as amounts of memory in in kilobytes,
|
||||
pages wired down (`wire'),
|
||||
active pages (`act'),
|

inactive pages (`inact'),

pages on the cache queue (`cache'),

they are not averages.
