Hi, best of three of time make -s install INSTALL=/bin/true
9.3: 1.53s 9.4: 1.55s 9.5: 1.90s 9.6: 2.10s 10: 2.45s 11: 2.81s master: 2.99s Obviously a part of that can be explained by the tree getting bigger, but that can't be all of it. It also gets a bit worse if LLVM is enabled (due to the bitcode files getting installed), but that's "just" 0.3s for me. We should optimize that for fewer install invocations / using cp, but that seems seperate. I think this also has gotten more pronounced with newer OS versions, as the overhead of the spectre/meltdown mitigations have increased the cost of syscalls and forks. Obviously this doesn't terribly matter for actual installations, but I do find it fairly annoying when running regression tests... Greetings, Andres Freund
