> How confident are you that the behavior of IE11 on Windows 10 inside a VM on OSX with outdated guest drivers and a prefpane only Cupertino understands is really similar to what a real user in say Bangladesh sees?
a) update your guest drivers.
b) what do you mean "only Cupertino understands"
c) does Bangladesh have some kind of specifically different "poor network" conditions that the rest of the rest of the world is not aware of?

For testing poor network connections? That is specifically what Apple's tool is designed for.

Bandwidth throttling is only one of the tools you need for performance testing. You may also need to, say, change the screen size and reported device resolution and user agent at the same time.
Chrome gathers all these tools and tons more under the same page. And they are specifically created for this purpose, hence probably more accurate than some OS specific implementation.
