I see that we install with: MOZ_MAKE_FLAGS='-j<number>' \ make -f client.mk install INSTALL_SDK=
For the build, if MOZ_MAKE_FLAGS are not set, it will use the available number of processors and the switch seems fine. But for the install, it appears to me that it does not do that, and in any case most of the install is single-threaded stuff (some python, then tar). Doing repeated DESTDIR installs, the first obviously takes longer (36s, nothing in buffer cache), but after that the difference between -j4 and -j1 was <15 and <20 seconds. To me, that seems a wasted line in the book, but then I do not generally like to run more than -j1 during installs, things have broken too often in the distant past. But rather than just impose my views, I'll ask first. Maybe I'm missing something useful. ĸen -- Nanny Ogg usually went to bed early. After all, she was an old lady.
