C++ Performance Traps: Hidden Costs of Abstraction and Compiler Optimization Pitfalls

Modern C++ performance suffers when seemingly harmless abstractions—such as virtual functions, hidden copies, non‑trivial destructors, overused std::shared_ptr, type‑erasing wrappers, std::variant/optional, and std::async—prevent inlining and efficient memory use, while patterns like std::move on returns, hidden destructors in tail recursion, and branchy loops thwart NRVO, tail‑call, and auto‑vectorization optimizations.

Zero‑Cost Abstractions: Principles, Benefits, and Rust Examples

The article explains the concept of zero‑cost abstractions, their two core requirements of no global overhead and optimal performance, adds a third focus on developer experience, and illustrates these ideas with Rust’s ownership model, iterators, async/await, and unsafe modules.
