The Chrome 41 Bump

Patrick Meenan mentioned first paint time improvements in Chrome 41. I noticed a ~25% improvement in the first view SpeedIndex times for one of our tests. It was easy to spot when the auto update from Chrome 40 to 41 happened:

I compared the individual tests before and after the update and this really is all about first paint times. The total time for the page to be visually complete was roughly the same.

WordPress.com #3 in Worldwide DNS Performance

Two weeks ago I mentioned dnsperf.com. After that I reached out to @jimaek about adding WordPress.com to the list of measured providers.

It has been super exciting to see WordPress.com DNS performance rank #3 worldwide:

dnsperf-wpcom-1

We are behind second place EdgeCast by just 0.66ms.

Serious kudos to our systems and network operations teams on including DNS as part of our Anycast network, which made this level of performance possible.
