I can't put numbers on it as the codebase no longer exists in that form, but I can tell you what I consider "unbearably slow". "Unbearably slow" is when the compiler takes too long for me to stay focused on a single task. So compile times in the minutes are a blow to my productivity. The machine is i7, 4 cores, 8G RAM, SSD. Definitely not as beefy as it should be. But my point isn't about how to optimize C++ compile times by adding more hardware. It's about the relative impact of "modern" C++ compared to traditional C++. There shouldn't be a disincentive to using modern libraries.
