Performance Optimization Techniques: Replacing Protobuf with C++ Classes, Cache‑Friendly Structures, jemalloc, and Lock‑Free Designs

This article presents practical performance‑optimization strategies for high‑throughput C++ services, including replacing Protobuf with hand‑written classes, adopting cache‑friendly data structures, using jemalloc/tcmalloc instead of the default allocator, employing lock‑free double‑buffer designs, tailoring data formats for specific workloads, and leveraging profiling tools to measure gains.
