We're running our builds and tests on both Windows 10 and Linux. At least for Windows 7, the compiler start up time had a huge impact on total run time. I think back then we had 2500 tests, each compiled, then linked, and then dwarfdumped and then some more tools (we build a compiler). We moved some stuff to Linux (eg dwarfdump) and saved a few program executions by compiling & linking single c file tests in one step (yeah, the driver still calls everything, but the driver is called once less). I was under the impression Windows 10 improved on that (we didn't benchmark in detail since then, since it's still far enough), but on Linux I don't have to bat an eye on eg make -j32. BTW, the author messed up anyway. Make -j does schedule everything at once. How do I know? Only way I got my private 128GB build host to oom...
