If you go for fastest then C++ with its own standard library plus add a few third party ones will get most stuff done. Look here: https://en.cppreference.com/w/

If you go for fastest then C++ with its own standard library plus add a few third party ones will get most stuff done. Look here: https://en.cppreference.com/w/cpp/links/libs https://en.cppreference.com/w/cpp/links/libs Pick header only libraries if you are concerned about portability. Now C++ is a pain in the ass to work with, and the world has moved on to better more convenient things. Do explore modern C# and Go for better developer productivity.
