Start of a new series at my Meeting C++ blog: About alignment, struct layout and the cache… by Jens Weller from the Article: A good overview on this topic are the two talks by Jonathan Müller: his talk on Cache friendly C++ from Meeting C++ 2025, and his talk on writing cache friendly C++ from Meeting C++ 2018. I got to watch his talk during the 24h++ event I’ve organized in December 2025, around this time also a question about padding bytes was asked on a LinkedIn comment in one of my posts.
