Apple is "biasing" towards IPv6: http://bit.ly/1D66PRV  - tl;dr serving A records (IPv4) will result in a 25ms delay!  IPv6 all the things.

One of the big complaints about Chrome currently is that it's a battery hog, especially on Mac where Safari seems to do better.

The team has been working on addressing this; here are some cases that have recently been improved on trunk:

http://crbug.com/460102

Before: Renderers for background tabs had the same priority as for foreground tabs.
Now: Renderers for background tabs get a lower priority, reducing idle wakeups on various perf test, in some cases by significant amounts (e.g. 50% on one test).

http://crbug.com/485371

Before: On a Google search results page, using Safari's user agent to get the same content that Safari would, Chrome incurs ~390 wakes over 30s and 0.3% CPU usage vs. Safari’s 120 wakes over 30s and 0.1% CPU usage.
Now: 66% reduction in both timer firings and CPU use. Chrome is now incurring ~120 wakes over 30s and 0.1% CPU use, on par with Safari.

http://crbug.com/489936

Before: On capitalone.com, Chromium incurs ~1010 wakeups over 30s vs. Safari's ~490 wakes.
Now: ~30% reduction in timer firings. Chrome is now incurring ~721 wakeups over 30s.

http://crbug.com/493350

Before: On amazon.com, Chromium incurs 768 wakups over 30s and consumes ~0.7% CPU vs. Safari's 312 wakes over 30s and ~0.1% CPU.
Now: ~59% reduction in timer firings and ~70% reduction in CPU use. Chrome is now incurring ~316 wakeups over 30s, and 0.2% CPU use, on par with Safari at 312 wakes, and 0.1% CPU use.

The Chrome team has no intention of sitting idly by (pun intended) when our users are suffering.  You should expect us to continually improve in this area.

Browser Progress Bar is an anti-pattern: http://bit.ly/1diGHfR.

First off, there is no way to correctly estimate or measure progress. Second, the success criteria (onload) is an increasingly less than useful concept. With that in mind, it's probably a good time to revisit what the busy indicator means and when it's triggered by the browser.

Step one: don't use a god damn HTML engine for your UI, and transpiled domain-specific languages for the wrong domain.

Step two: there is no step two. You just stopped misuing document technology for UI technology. Good job!
