Yeah. So I forget the original tuning I did for that project. But, I fill up a buffer which is on its own cache line (Chunk) and then signal that the chunk is ready for ownership on the other side, thus sending it. I’m not sure why the signaling atomics aren’t on their own cache lines, I imagine I tried both and this was faster? There’s also a chance I never tried it because I felt I didn’t need it? I’m not sure!
