Hello, Ulrich Drepper's piece on on-chip memory architectures is a fantastic read, and I recently had the chance to revisit it -- https://people.freebsd.org/~lstewart/articles/cpumemory.pdf I am writing to ask more knowledgeable folks if the last 13 years have seen sufficient changes that render parts of this out of date or misleading on 2019 hardware. Cheers! -- Boyan Penkov
