What is faster: JMP or string of NOPs?

Question

I\'m implementing binary translation and have to deal with sequences of NOPs (0x90) with length about 16 opcodes. Is it better for performance to place JMP (to the end) at s

Answer 1

If the NOPs are to align the stream, then they have more value than just being a NO OP. if your concerned with pure speed, see Agner Fog's Optimization Manuals Vol. 4.
