How Much Linear Memory Access Is Enough? (probably less than 128 kB)

Typical performance advice for memory access patterns is "keep your data contiguous". When you think about it, this must have diminishing returns. I tried to experimentally find generalizable guidelines and it seems like 128 kB is enough for most cases. I wasn't able to find anything needing more than 1 MB really (within the rules). submitted by /u/PhilipTrettner [link] [comments]
