This article explains the core principles of memory alignment on Linux, shows how misaligned data harms CPU cache and execution speed, provides concrete C code examples and benchmark results, and offers practical techniques—including compiler directives and struct layout tricks—to achieve optimal performance.
This comprehensive guide covers the core Go concepts most frequently asked in interviews—including goroutine scheduling, channel communication, interface internals, garbage‑collection mechanics, toolchain utilities, error handling patterns, and struct memory layout—providing clear explanations, code examples, and practical tips to help candidates transition from writing Go code to truly understanding the language.
This article explains the concept of memory alignment in Linux, how alignment rules affect struct layout and CPU access, why proper alignment improves performance and portability, and provides practical compiler directives and code examples for implementing and testing aligned data structures.
