Hi. CPUs are highly HIGHLY optimized to do what they usually do at least as quickly [and, for the most part, much more quickly] than one can do by cobbling it together another way. If you are asking “How can Julia outperform C++ in some cases?”, see [this thread.](https://discourse.julialang.org/t/a-bet-what-specific-algorithms-in-julia-can-be-faster-or-as-fast-as-c-implementations/13564/)
