In the modern era with multiple CPUs the norm, I was interested in
finding a way to speed up compiles from source (of the kernel and
the various ports I use).
According to the man page "make(1)" the "-j max_jobs" option:
Specify the maximum number of jobs that make may have running at
any one time. Turns compatibility mode off, unless the -B flag
is also specified.
While building the kernel today, I was successful using "make -j 4"
on a four CPU system. Later on, on the same system, I was unable
to build any ports from source using either "# make -j 4 install"
or "# make -j 2 install" commands. What am I missing here?
