Very relative term there ... "almost"...:-).
You have approximately 250 MiB available and practiacally no swap
activity... Looks pretty well-balanced to me. Load seems reasonable,
especially if you run sendmail.
The TIME there.... How long ahd the process that took 2:34 been
running? Assuming close to 4 hours on a fairly busy server, then using
the CPU for well under 3 minutes total isn't much to write home
about:-). What I'm saying is that performance measurements without a
context and with no "baseline" to compare to, is pretty useless;).
