Measure the Performance of each Release

[supernova-at]

Summary

Create a document (internal? public?) that tracks PWA Releases and the performance metrics identified below.

_{As part of this ticket, please also create a document that describes exactly how we measure each, so that it is trusted and repeatable. See the research issue.} This work has been separated out into #1710.

Metrics Identified

Built / Deployed Asset

• Bundle size (including number of bundles + size of each)

PWA Demo Site

For the Venia reference storefront located at https://venia.magento.com.

• First Contentful Paint
• First Meaningful Paint
• Time to Interactive
• Speed Index
• First CPU Idle
• Max Potential First Input Delay
• Time to First Byte

Measure Accessibility, Best Practice and SEO Scores across page types for each release

[supernova-at]

The idea is that this "metrics collection" would be done as part of each release.
