tracking down a response time problem I noticed the following on Compaq's
web site.
The values in the memory fields are specified in 8-KB pages. Check the size
of the free page list (free).
Compare the number of free pages to the values for the active pages (act)
and the wired pages (wire). The sum
of the free, active, and wired pages should be close to the amount of
physical memory in your system. Although
the value for free should be small, if the value is consistently small
(less than 128 pages) and accompanied by
excessive paging and swapping, you may have a physical memory shortage.
My system has 384 of memory.

It seems that when I add free (19K), wire (23K), and fault (4293), this
suggests I have a memory problem, is this correct in your view??
Thanks
