but that would true only for cooperative scheduling,for pre-emptive scheduling atleast
for a single event/interrupt time would be
=scheduling time+context switch+delays due
to non preemptible kernel portions.

from my experience(however little it is)
context switch in 8051 architecures is the
most time consuming part because of iram-xram
architecture.
