#### Editor’s note
|
| |
|
In the last few years, tooling available in browsers to analyse and profile web performance has exploded. We also have a wide range of open source and paid tooling available on multiple platforms to help us with specific areas and issues.
But, since performance often happens in the browser, the question remains: can vendors do even more to optimise the fetch and render process? I think yes, but these are not easy waters to thread. We might be looking at lengthy timeframes between establishing inevitably opinionated strategies for optimal performance to shipping stable versions. Still, getting more built-in tools and documented processes directly in browser internals can be invaluable.
We already have fast browsers. Now, let’s get to browsers enforcing fast sites and apps!
