-j <number of parallel make processes>

So: [joe:/usr/src/linux] make -j 3 bzImage

will build bzImage using a maximum of 3 parallel makes.
This is only likely to help much on multiprocessor machines,
where -j N = number-of-processors. On a single processor
you may see some improvement, or not, depending on
disk bandwidth and RAM constraints.
