Don't modern processors have more cache available between all cores than available to a single core?

- jayd16 6y agoThey must mean its memory I/O bound.
- foota 6y agoI think they meant it only runs quickly enough when everything's in cache? But that doesn't make much sense to me. It's really hard for me to believe it'd be I/O bound though, when memory bandwidth is like tens+ of gigabytes per second?
- imtringued 6y agoIO bound can also mean that memory latency is a problem. It's not difficult to believe that DF is doing lots of pointer chasing.
