For memcpy and memset, they are usually memory bound, so it isn't surprising that it doesn't get to 1 instruction per clock. I wonder if this is due to slow mem

For memcpy and memset, they are usually memory bound, so it isn't surprising that it doesn't get to 1 instruction per clock. I wonder if this is due to slow memory instead.
- kragen 4y agoSeems likely. Or maybe they don't have any cache and so it's spending half the memory bandwidth on instruction fetch? That can't be the Pi's excuse, though.
