This has probably been discussed before, so apology for
asking the same question again.
Should the Active memory, as reported by top(1), be equal to the
sum of rss (the real memory (resident set) size of the process)
of all processes, as reported by ps(1)?
The sum of ps(1) rss fields is probably the same as
the sum of RES fields of top(1).
I seem to have much bigger Active set than the sum of
all resident (or real) memories used by all processes.
