I sent it out more because I'd written it and it works and is a useful demonstration of meson+ninja performance. Obviously 20 seconds -> 5 seconds isn't a huge deal :); but in a larger project, consider that a 4x speedup would be 4 minutes to 1 minute, and that is a huge difference in time. > > As the port is not 1:1 wrt the autoconf one, the performance numbers > above are comparing apples to oranges. I fail to see what I'm missing from meson that would have an effect on the times I reported. There are some files that are installed by autoconf that I didn't bother to install with meson (because I don't expect this to land). Since I didn't time installs, I don't see how it isn't an apples to apples comparison. I understand that libdrm is a pessimal case for recursive-make since most sub folders contain < 5 C files, However, even if you were to flatten the make files meson+ninja would still be faster when you consider that meson configures and builds faster than autotools configures. > If you/others are unhappy with the build times of libdrm - poke me on > IRC.
