Cliff Click's Crash Course In Modern Hardware 249
Lord Straxus writes "In this presentation (video) from the JVM Languages Summit 2009, Cliff Click talks about why it's almost impossible to tell what an x86 chip is really doing to your code due to all of the crazy kung-fu and ninjitsu it does to your code while it's running. This talk is an excellent drill-down into the internals of the x86 chip, and it's a great way to get an understanding of what really goes on down at the hardware and why certain types of applications run so much faster than other types of applications. Dr. Cliff really knows his stuff!"

Probably due to your x86 processor doing all sorts of monkeying with the code.

The first four minutes of the video are spent asking which topic the room wants to see. No need to watch that part. Then it gets more interesting.
That's just the branch predictor pre-loading the cache for each possible conditional result.

Spaghetti code can be hard to digest.
Sounds to me like someone is using stale Copypasta.
