I think both have been significant, but I agree that top performance is not so much an issue for many applications (although JS is also very fast). > I suspect that C++ is over-represented in multimillion line codebases. You're right, but the question is compared to what? Java, C++ and C are pretty much the only languages used in multi-MLOC codebases maintained over many years (there are others, but not nearly to the same degree as those three) so they're all over-represented, but the amount of C++ and C code is significantly lower than that of Java code. I think it's due to maintenance costs (as a maintainer of a C++ codebases over my career, that's been my experience, but I try not to extrapolate so I consider this my unproven hypothesis).
