Well, I used both "top" and the System Monitor>System Load simultaneously (each running in a different workspace) to see what was happening during the copy processes using mc to copy the 11.1GB file to ext4 and ntfs partitions.
Sorry to disappoint, but I could not see any core "maxing out" during copying. The load was being distributed across 5 or possibly 6 cores (with wither 3 or 2 being almost idle). With the data jumping around from core to core it was just a bit hard to keep up :-) , but I did see that the max any single core reached in both cases (ext4, ntfs) was 74% - with, as I said, either 3 or 2 cores doing almost nothing).
Curious. So the load was distributed on the cores... interesting. That's more complicated to analyze. There may be other issues in play. I'm guessing memory moves, and thus, board and memory bandwidth, but dunno how it can be diagnosed. Alternatively, the task is jumping from core to core, but nevertheless it is not running paralellized. On average the load would be low, but the cpu where the job is running, peaks. - -- Cheers, Carlos E. R.
