In-Depth Information
• Set “Number of parallel jobs”. This value will be passed to
make
to accelerate the
build time for the cross-compiler toolchain. Setting this value too low will make
the build take longer than it needs to, but setting it too high will result in the CPU
resources being spread too thin (and will also make the build take longer than it
needs to). The magic value seems to be the number of CPU cores in your system
multiplied by 1.5. On our 8 core laptop, this is
12
. If you're not sure how many CPU
cores your system has, run:
$ cat /proc/cpuinfo |grep processor
Count the number of lines, as each CPU core will appear to Linux as a unique pro-
cessor.
