Page Bloat: The Average Web Page Size Is More than 2MB
I’ve been tracking the typical web page weight and composition of the top million websites (thanks to the HTTP Archive) since 2011. Back in 2012, it was huge news when the average page exceeded 1 MB. At the time, people were incredulous…and even outraged. And they almost immediately began to speculate about when the average page would crack the 2 MB barrier. It looks like the speculation can end now.

Here’s Why More Bandwidth Isn’t a Magic Bullet for Web Performance
One of the most common arguments I hear when people rationalize why things like page bloat aren’t that big a performance issue is that ever-evolving networks mitigate the impact. In this post, I’m going to demonstrate that increasing bandwidth up to 1233% makes pages just 55% faster — meaning that faster networks aren’t the performance cure-all that some folks assume they are.

Improving Single Page Application Monitoring with Boomerang
We’ve learned a lot from our customers and how they are building their single page apps (SPAs). Many of our monitoring improvements are being driven by the variety of websites that our customers are building, using everything from do-it-yourself templating engines to full-blown frameworks such as Angular, Backbone.js, Ember.js, or React. There are two key things we’ve learned, which have...

Setting Up SSL on nginx for Performance and Security
At WebPerfDays Silicon Valley 2013 we ended up with an intense debate about the usefulness of SSL vs. the performance of SSL. The primary problem seemed to be that there was no simple, step-by-step guide on how to set up SSL correctly. Now, I’m no expert on SSL performance, but I did have to learn how to set SSL up...

The Non-Blocking Script Loader Pattern
Way back when, in the early days of web performance (ca. 2005), the suggested way to embed third-party scripts in web pages was to use a straight up <script> node. This was simple, and what happened next was deterministic. The rest of the page blocked until this script node had loaded and executed. <html> <head> <script src="http://some.site.com/script.js"></script> <!-- And now...
