We probably need to know a bit more about how you're building things.
Do you have a pool of workers building against a common sstate?

Are you using hash equivalence? Are you using a PR server?

I ask the questions as the answer is probably somewhere in the way data
is being shared/reused between builds.

If you're not using package management on device to upgrade them, it
probably isn't a big issue but it is worth understanding the sstate
reuse in this context.
