An outgoing request from a whitelisted domain returns a 302 , forwarding the request to a self-hosted CSS file that is optimised specifcally for your browser, OS, and UA (Google Fonts do something similar). So, what are the performance implications of all of this? com , which introduces yet more latency for the connection setup.

Engine diversity is essential, as it is the mechanism that causes competition to deliver better performance, capability, privacy, security, and user controls. Google's Search App and Facebook's various apps for Android undermine these choices in slightly different ways. [3] Et Tu, Google? #. More on that when we get to iOS.

The authors also observed explicit sampling jobs that perform some complex and detailed computation on a sampled relation, without ever correcting for the effect of sampling. Hence, query optimizer transformations which push samplers down without affecting plan accuracy can improve performance. Of the other 14 all but one improve.
