Apart from the best practices that can often be automated, there are many human decisions that have impact on page speed. A way to make page speed part of the conversation and optimising it part of a website’s requirement, is to set a performance budget.
This is a great blow-by-blow account of making an agency website perform better.
I love the side-by-side comparisons with other agencies, including Clearleft—the gauntlet has been thrown down!
Google’s experimental new “slow” label could revolutionize how we tackle web performance - Web Performance Today
It looks like Google is going to start explicitly labelling slow sites as such in their search results (much like they recently started explicitly labelling mobile-friendly sites). So far it’s limited to Google’s own properties but it could be expanded.
Personally, I think this is a fair move. If the speed of a site were used to rank sites differently, I think that might be going too far. But giving the user advanced knowledge and leaving the final decision up to them …that feels good.
Some good practical advice from Tim on setting a performance budget.
Use rule-based metrics to make sure you haven’t overlooked simple optimizations.
Use quantity-based metrics as guides to help designers and developers make better decisions about what goes onto a page.
Some sensible thinking from Tim on measuring performance gains.
Some handy tips for simulating slow network speeds on your machine.
This is just wonderful! It combines almost all of my recent obsessions into one unified post: website performance (particularly on mobile) and the locations of undersea cables. The interactive map is the icing on the cake.
Some good practical advice on improving performance. This should all be familiar to you, but it’s always worth repeating.
A handy performance testing tool from Pingdom, similar to Google’s offering.
Jason reiterates Bruce’s rallying cry: Performance First!
If you could only do one thing to prepare your desktop site for mobile and had to choose between employing media queries to make it look good on a mobile device or optimizing the site for performance, you would be better served by making the desktop site blazingly fast.
Bruce hammers home the importance of speed and performance on mobile (and frankly, everywhere).
So perhaps some of the time and effort put into media queries, viewports, avoiding scrolling, line length would actually be better employed reducing HTTP requests and optimising so that websites are perceived to render faster.
A script that attempts to detect connection speed (by requesting a test file three times in a row) in order to determine whether hi-res images should be requested or not.
I like this ad-hoc approach to staging one-night-only internet art shows:
Hit an Internet-cafe, rent all computers they have and run a show on them for one night.
Performance matters. Here, the Washington Post compares its own weak performance (hampered by ads and tracking shite) to the optimised experience of porn sites.
Performance shit just got real.
You can now sign up with Google to have your site pass every request through them and get your documents served up optimised.
A handy tool for checking page load times.
An online book about website performance by Stoyan Steganov, released into the public domain. Excellent!
Great news! Google Analytics now tracks page load times.
Freaky stuff. If you’ve seen Kevin Slavin or James Bridle talking about the increase in property prices on Wall Street as the buildings get closer to the network hub …that’s nothing—these are the new centres of world power; places where the speed of light interferes least with the speed of transactions.
A supremely useful tool from Google for measuring performance.
This is wonderful stuff: a long-term project to track the performance of high-traffic sites over time: oodles of lovely data and some quite shocking stats.

Brian Suda has a theoretical solution to real-time interplanetary communication: "I get on my tachyon voip phone and make a call from mars to earth at 9:00am it takes 10 minutes to travel there, but the tachyons travel backwards (so i think) that would be
