You're right to emphasise good data-structures and algorithms (also concurrency, parallelism, etc), but compiler optimisation is nothing to sneeze at. '10%' is laughably off-base.
From a quick google: compiler optimisation can accelerate CPU-bound code to over 5x the unoptimised performance. https://www.phoronix.com/scan.php?page=article&item=clang-gc...
