I ran some tests on my dual-Xeon machine to see what speedup using
parallel gmake. After two builds to warm up the cache, I saw when
alternating gmake and gmake -j2:
gmake -j2 0m44.305s
gmake -j2 0m33.979s
As you can see, gmake -j2 is ~35% faster than gmake without -j. I will
be using -j from now on. -j3 shaves another second off.
FYI, I also use ccache for compiles.
