    Something to do with pipelining. To increase the speed it will be loading the next instruction while it is executing the current one. With some instructions it has to flush the one it's just loaded because the program branches somewhere, and start from scratch.

    Yes. Most of the instructions will be 12 times as fast, some only about 5 times as fast.
