1. AN OVERWEIGHT PROBLEM
“We've remade the Internet in our image… Obese.” – Jason
Grigsby –
The average webpage is 1.617MB. Mostly images. httparchive.org
milwaukeepolicenews.com
milwaukeepolicenews.com 7MB
redrobin.com
redrobin.com 10.9MB
grolsch.com
grolsch.com 25MB
moto.oakley.com
moto.oakley.com 85MB
Just because we can, it doesn’t mean we should.

74% of mobile users won’t wait longer than 5 seconds
for a page to load bit.ly/5secondsmobile

2. THE IMPORTANCE OF BEING MOBILE FIRST
Content First?
User First?
Everything First!
Reduced Browser Window In Developer's Computer First
Worry about the less capable first
None
Design around real content
1 column of content + basic styles
body{max-width: 30em;}
Consider layout an enhancement: inside @media queries
@media screen and (min-width:1px){ body{ max-width: inherit; } }
<!--[if lt IE 9]> <link href=“ie8.css" rel="stylesheet" /> <![endif]-->
github.com/scottjehl/Respond
Enhance with JavaScript
if( 'querySelector' in document && 'localStorage' in window && 'addEventListener'
in window )
Cutting the mustard
None
Conditionally load: secondary assets third-party content transitions, effects AJAX stuff
Design agnostically
Design for every input
None
Design for every context
Design for every connection
3. OPTIMIZE ALL THE THINGS!
The average webpage is 1.617MB. Mostly images. httparchive.org
Can we afford another image?
Try to serve the right image size
adaptive-images.com
github.com/scottjehl/picturefill
Do retina devices need retina images?
netvlies.nl/blog/design-interactie/retina-revolution
Optimize images: ImageOptim JpegMini SVGO
Optimize everything: reduce requests combine & minify gzip
JS files belong on the footer
Do we need a JS framework?
Avoid or conditionally load: iframes social plugins third-party assets
Consider plain links for social stuff

There’s so much we can optimize
None
4. PERFORMANCE BUDGET
“We’ll do it later” is a lie
Performance as a design principle
“Make the page usable in less than 10 seconds on
a GPRS connection.” – BBC News –
First load: somewhere between 65KB and 100KB
“Don't make more than 20 http requests”
“Make the page weigh less than 300KB”
“1. Optimize an existing feature or asset. 2. Remove an
existing feature or asset. 3. Don’t add the new feature or asset.” – Steve Souders –
5. PERCEIVED PERFORMANCE
Avoid JS redrawings

wow such design very icons so flats nice font wow

Set a performance budget in the design workflow
“What a fast website, that on top of that, is
beautiful.”
