    The specific architecture & topology of your CPUs, interconnects, caches and memory does affect performance. Unfortunately no general analysis of this is likely to fit in an answer here, so you really need to describe all of those things (plus your program's access patterns, how performance varies with dataset size, and what profiling you did) to get anything resembling an answerable question.

  • To start with, you can look at things like numastat (on Linux) and whatever perf counters your OS/CPU offer to get an idea of what changes as your dataset grows. Commented Nov 8, 2022 at 17:00
