To improve speed, try running a parallel build. That's done by default in Ninja; for ``make``, use the option - ``-j NNN``, where ``NNN`` is the number of parallel jobs, e.g. the number of - CPUs you have. + ``-j NNN``, where ``NNN`` is the number of parallel jobs to run. + In most cases, you get the best performance if you specify the number of CPU threads you have. + On some Unix systems, you can specify this with ``-j$(nproc)``. * For more information see [CMake](https://llvm.org/docs/CMake.html) |
