Why You Shouldn't Forget to Optimize the Data Layout (12 minute read)
The way data is organized in memory (data layout) can impact a program's performance. Choosing the right data layout, such as Array of Structures (AoS) or Structure of Arrays (SoA), can optimize cache line access and leverage vectorized instructions (SIMD) for faster execution. SoA, for example, can be much faster for reading operations, especially when combined with lightweight compression techniques like frame-of-reference encoding.
