I'm just curious on what RMW stands for and what it means
Despite of not knowking programming, I know ADD/SUB/INC/SHL etc. are assembler nemonics, and I don't like to ask what I can google, but I can't find anything regarding RMW

Read-Modify-Write, something like: add [rsi], 10

On older x86 cpus such instructions are slower than Read, Modify + Store blocks, but on nowadays it outcomes at same instruction speed.
RMS:

mov rax, 10
add rax, [rsp]
mov [rsp], rax
