Most apps don't have heavy-weight algorithms that benefit from big-O optimization. So, performance is decided by the speed of common language elements (function calls, memory allocations). It will be more effort, and harder to make secure, but you will most likely see a performance gain when using a systems language. And even more so, C++ has more escape hatches (custom memory allocators, multi-threading) than Python.
