build time is crazy
Hello guys !
I'm using t3 + turborepo, which looked like a very promising solution.
Unfortunately, the build times are completely out of control. 45 seconds for a simple pages, dozens of minutes for a full build.
did you have a similar experience ?
my build script is
"build": "pnpm with-env next build --turbopack",
the dev is
"dev": "NEXT_TURBOPACK_TRACING=1 pnpm with-env next dev -p 3030 --turbopack", with next: ^15.3.0 and react 19.1 in my page folders, i have a layout with a "prefetch" and a page with "useSuspenseQuery" do you see anything that could be wrong or any antipattern here ? I added my trace analysis if it helps you understand Thank you so much for your help ❤️

From my experience, turbopack building is not fully optimized for production still. Try back to use webpack for build;
Do not append NEXT_TURBOPACK_TRACING=1 in dev command. Disable it to avoid extra overhead.
To avoid long build time, do not use useSuspenseQuery in layout level. Only use it in individual page/components level.
Also for deep large layout trees, do not use prefetch. Simply disable it like prefetch={false}
