This article explains how to accurately measure the execution time of Objective‑C methods on iOS by implementing a custom objc_msgSend hook in ARM64 assembly, replacing the original implementation with fishhook, and visualizing the results using Chrome tracing, offering a low‑cost, non‑intrusive performance profiling solution.
This article details how 58 Tongcheng improved iOS app startup speed by defining launch time, building automated measurement tools, detecting slow methods via hooking, applying binary reordering with Clang sanitizers, and implementing dynamic library lazy loading, achieving significant reductions in launch latency and page faults.
Learn how to create a custom Spring Boot starter named aspectlog-spring-boot-starter that automatically logs method execution times using AOP, covering project setup, Maven configuration, conditional loading, annotation definition, auto‑configuration class, META‑INF registration, and packaging for reuse in other projects.
