It's deceptively harder to interpret assembly nowadays with more and more niche instructions that may take hundreds of clock cycles to execute

- _tom_ 4y agoSo much of performance is memory access now. The instructions can be fine and the access pattern wrecks you.
- adrian_b 4y agoYes, indeed. Now any load from the L3 cache memory or from the main memory takes much more time than any other instruction (not counting exceptions generated by instructions, which include many memory accesses that slow them down, or deprecated instructions that are kept for backwards compatibility and that are executed by long microcode sequences).
