If you program in assembly and your program needs just 2000 cycles a node, then 0.5% means saving out 10 cycles lossless. That's independant from search changes and eval improvements. It is very hard to save 10 cycles at very well programmed and hand scheduled assembly code. To litterary quote Frans Morsch when someone complained that after some changes his amateur program was 'only 20%' faster: "Be happy you still can improve so much, I work for 6 months to get 0.5% faster".
