linux - Spawning Multiple Jobs for building a kernel on Quad Core processor? -

if kernel's makefiles have correct dependency information,

to spawn mutliple jobs, should use this

$make -jn  

n = number of jobs spawn

if use quad core machine i7 4700mq 8 gb ram, should ideal , maximum value of n ?

grep '^processor' /proc/cpuinfo | wc -l 

it should give number of cpu's in system (as seen os). can use number. +1 number usualy won't hurt (it depends on project building, scheduler in use, etc.).
