Why does the order of the loops affect performance when iterating over a 2D array?
...ht?
No: because of caches. Data from your memory gets brought over to the CPU in little chunks (called 'cache lines'), typically 64 bytes. If you have 4-byte integers, that means you're geting 16 consecutive integers in a neat little bundle. It's actually fairly slow to fetch these chunks of memory...

Why would introducing useless MOV instructions speed up a tight loop in x86_64 assembly?
...ome work in that area. But we're talking a minimum of 5-10 minutes of 100% CPU to compile, and the resulting optimizations would probably be CPU core model and even core or microcode revision specific.
