Monitoring your sites for key performance metrics like Page Load or Visually Complete is important, because it helps uncover errors, outages, and critical defects. When performance degrades, you have to figure out why. While reading a waterfall diagram can help provide insight into what the browser was doing, you are still trying to reconstruct what the user experienced by looking at a timeline showing when a browser requested and received content. This is kind of like trying to experience a Broadway musical by only reading the sheet music. To...

Web Perfectionist 101: Source Maps and Minification

Jennifer Carlson

In this week's Web Perfectionist 101 episode, Billy discusses source maps and how they can help to minify files for enhanced web performance.

The Optimization Tools Rigor Uses

Billy Hoffman

People often ask what optimizations tools Rigor uses internally when optimizing content, or why our root cause analysis product Zoompf flags a piece of content as unoptimized. While I wrote about comparing PNG optimizers several years ago, I thought it would be helpful to explain what tools we use detecting unoptimized content. Keep in mind these tools wouldn't necessarily create the smallest possible optimized content. Performance tools often have a trade off between time, CPU, and resource usage, and how small the output file is. Some tools...

In my Optimizing HTML5 Video presentation, sharp eyed readers may have noticed I mentioned some performance optimizations in passing about video sizing, quality, and bitrates, which we haven't discussed on the Rigor blog before. A brief note on a slide doesn't fully convey the full reasoning or benefit of these optimizations. So today, I will talk about 3 additional ways you can optimize your site's HTML5 video performance with proper sizing, quality, and markup. As we will see, you can detect these additional performance issues manually fai...

Optimizing HTML5 Video – Presentation Slides

Billy Hoffman

Earlier this month I was invited to speak at the Atlanta Web Performance Meetup group. My topic was Optimizing HTML5 Video, something I have covered extensibly on this blog. We had a large turn out and the audience asked some great questions. One attendee was kind enough to post this feedback on our message board: The entire reason I started looking at video content in general, and HTML5 video specifically, is how shrouded in mystery online video is. While many people know various lossless and lossy optimization techniques as well as tooling...
