Internet Explorer There's a bit of a ruckus on the web about how Microsoft was supposedly cheating when it comes to Internet Explorer 9's performance on benchmarks. Digitizor, as well as some enterprising readers over at HackerNews, came to the conclusion that Microsoft included code in IE9 specifically to ace the SunSpider benchmark. I was ready to write a scathing article about this, - until I loaded up the IEBlog. As it turns, it's not cheating, it's not a bug - it's an actual piece of smart code optimisation other browsers don't have yet.

Being closed source and bugs being hidden behind the most hideous of login walls doesn’t help with transparency when it comes to this problem. They did the right thing in explaining clearly on the blog though.

Incredible how people are!

As if Microsoft was ever convicted for bad businesses practices, for breaking monopoly laws, or for screwing with "parteners".

as if they weren't punished for such crimes and have changed such practices in the 15 years since committing them.

Well it's certainly not hard to understand how people could get that notion if they had ever written code.

Adding either of these two, a 'true' and a 'return' which both does nothing in the context of this code and thus would certainly be optimized away as dead code suddenly prevents this dead code elimination optimization that before either of these (again, doing nothing) changes was able to optimize away the entire function.

But even so I don't think they are cheating, I believe this is due to the 'frailty' of their dead code eliminator, which as proven by this needs more work.

I've seen alot weirder things than this in my days as a programmer and I can't see why the IE devs would cheat this way if they were interested in cheating (which I don't think they are, I may have issues with Microsoft as a company but I have nothing but respect for their developers and no self-respecting dev would do something like hardcoding a dead code elimination, not even with Ballmer breathing down their necks).
