.. is 50% chance to die by thousand paper cuts, 25% simply wasted time, AND 25% chance to avoid death by thousand paper cuts. At least in image processing and robotics, from my experience. It's very annoying when you have optimized all obvious hotspots 10x only to get 3x speedup because the remaining 30% code consistently abuses « simple ways », e.g. return big objects by value, use std::vector instead of proper Eigen arrays, constantly serialize objects everywhere, etc.
