🅽 Why Images Hurt Your App's Performance and How The New Image Component Can Help - @atcastle

Problem: Oversized Images
Solution: `Image` component that will generate srcset w/ image optimisations

Works w/ 3rd party hosting + auto-formatting
Problem: Too many Images
Solution: Default to Lazy Loading

Escape hatch using `priority` or setting `loading="eager"`
Problem: Loading CSS/JS are prioritised over images
Solution: Preload header for images by setting `priority` on the Image component (⚠️)

--
Me: Host images on a different [sub]domain to get around max concurrent limit per host. https://bit.ly/2TuttV0 
Problem: Content shifts as the images load
Solution: `Image` component will enforce height & width (ratio, no px required).

Opt-out using `unsized` attribute.

🅽 Future of Performance and Data in the Modern Web

@MongoDB will do Search, provide mobile SDK for low-latency changes with sync to cloud and Multi-cloud clusters.
@ianand:

There are two major things that makes a site slow:

You are either network-bound or CPU-bound.

And #JavaScript can hurt you on both of those.
