We write server software, running 24/7 by hundreds of thousands of server, so even double the development time on a single machine would be easily offset hundreds to thousand folds by a more efficient executable. But, you even need to go to C if you would like to achieve that, e.g., using rust gives you nice level of abstractions and is highly efficient.
