Yes. It's not real-world testing, but it's testing nonetheless. First time I reformatted a Windows machine and turned it into Linux, I had the surprise of my life. I had to re-run all my Oracle tests in case I had been measuring Windows not Oracle, the difference was that dramatic. I can't quantify it for you (well, I can say test were running at least 2, 3 and 4 times faster -identical machine, I remind you- on Linux than on Windows, but I didn't document that, and as I say, these were private stress tests, not a production run), but yes you will notice it.

Group regulars will affirm, I think, that I was once a dedicated Linux hater. Now I am merely incompetent on it. But despite that, I refuse to run Oracle on Windows any more. It was that much of a shock.
