What slows your frontend builds the most today?

In many frontend setups, build time increases not because of raw size,

but because the same work gets repeated over and over:

the same dependency graph rebuilt,

the same transforms re-run,

the same outputs discarded between runs.

the same dependency optimization!

We’re curious:

What’s the biggest build-time pain you’re dealing with right now?

Local dev? CI? Monorepos? Microfrontends?
