> Perhaps they are referring to how long it takes to propagate your changes in their “Global Edge Network” once actually deployed
Correct, global propagations happen in 300ms after deployment: https://vercel.com/changelog/faster-and-more-reliable-global.... You can try it out here if you would like: http://on-demand-isr.vercel.app
> The 20-30 seconds their own Next.js template takes to deploy.
Indeed, this is not where we want it to be. We want single digit second, or ideally sub-second deployments. We're actively working on making these faster.
> The only reference to Next.js Live
Being able to share feedback instantly on Vercel Preview Deployments through comments was the evolution of Next.js Live. This was for a few reasons. One, we wanted it to work with all frameworks, not just Next.js. And two, early customer feedback from the private beta told us customers wanted a tool that helped consolidate and bring feedback directly into the UI layer. Thus, comments were born (and we have more updates coming here in the future).
> it takes 9 seconds to generate a “production” build
We agree. This is why we're investing in Turbopack to speed up production builds: https://turbo.build/pack. We're also exploring other innovation in the bundler space that could help improve production build performance inside Next.js.
I'm still getting familiar with all the different tools involved. You mention Turbopack as something that will speed up production builds, but I'm seeing similar build times (using npm run build) with that demo project (npx create-next-app --example with-turbopack) as I was with the normal Next.js toolchain.
Is there any way to have the production build re-use build artifacts from a previous build so that my 1 line code change doesn't trigger an entire rebuild?
