Where are you putting the -j4? I have a small cluster I build with
and I add the -j4 flag to the Makefile/GNUmakefile.
For 21.1.x I add the following line just before the RECURSIVE_MAKE=
rule:
MFLAGS += -j4
For 21.2.x I just add the flag to the RECURSIVE_MAKE= rule:
RECURSIVE_MAKE=$(MAKE) -j4
This gets me the best utilization of all the proccessors. There is
more information on the cluster on my web site
http://netwinder.org/~seanm.
