--- Comment #13 from Janez Zemva <janezz55 at gmail dot com> --- @Jonathan Wakely I asked ChatGPT about this: What is the most common size of a cache line? The most common size of a cache line is 64 bytes. This size is used by most modern CPUs because it strikes a balance between the amount of data that can be stored in a cache line and the amount of overhead required to manage the cache. However, it's important to note that different CPUs and cache designs may use different cache line sizes based on their specific requirements and trade-offs between performance and resource usage. This means the "right" number is architecture-dependent and my proposals were not wrong for every possible architecture.
