JS parse time, after load, to get to interactive for your users. #ChromeDevSummit

All of this is the L, load, of Rail. Getting to interactive is hard, slow. #ChromeDevSummit

Network takeaways for increasing performance #ChromeDevSummit

HTTP/2 push plus service workers gives benefits of first load push w/o most downfalls of cache #ChromeDevSummit

Lazy loading makes for last discovery documents, which increases download times. preload helps minimize this #ChromeDevSummit

Use rel=preload to hint to browsers that link tags should be grabbed as they’ll be needed #ChromeDevSummit

The critical rendering path: what it takes to paint (not interactive) #ChromeDevSummit

The average load time on mobile sites is 19s #ChromeDevSummit

The mobile web is no longer a subset of the web. It is the web. @samccone #ChromeDevSummit

If I can’t interact with your app, beyond scrolling, in under 1s, you’ve failed. #ChromeDevSummit

Tools and techniques brought over from desktop era are hurting us. #ChromeDevSummit

Mobile networks are actually getting slower! #ChromeDevSummit

Mobile networks hate you. Mobile networks basically operate the opposite of how TCP was designed #ChromeDevSummit

Turns out flash isn’t always flash. Chip consolidation and low parallelism make for slow perf. Think spinning disks #ChromeDevSummit

The web is not optimized to work how mobile devices are optimized to run. #ChromeDevSummit

Thanks to power and thermal constraints, a large amount of the silicon in our phone is unused #ChromeDevSummit

Mobile phones don’t run a fast as desktops despite similar advertised speeds because they can’t burn your hand. #ChromeDevSummit

Optimize the motion mark benchmark on your phone by adding an ice pack! #ChromeDevSummit

The $700 iPhone in your pocket isn’t what the next billion people are going to buy when they come online #ChromeDevSummit

“Traces from real mobile devices are a harsh master” - @slightlylate #ChromeDevSummit

Why are our tools slow by default? Why don’t we fully get the constrains of the mobile web? #ChromeDevSummit
