> A question how resource constrained are the Arm buildbots?

We've got 6 agents for Arm, enough to build a single revision in parallel with ~40 minute average build time.

> The Apple builds will only build after the build before finish, this is done due to the fact the Apple build nodes are quite slow

And (I assume) because there's some finite number of them. If you wanted a faster pipeline and had infinite (but slow) agents you would put the Apple agents in the first part.

> If Arm isn't resource constrained it might be an idea to move this build directly after the "Unified standalone build

Whether 1 agent per config is "constrained" is gonna depend on how many builds get run and what your expectations are. Unless your gut reaction is "yes definitely" then I'd be happy to move them into the first set and find out, best way to find out.

(for the moment my logic is as long as they're as fast or faster than the Apple builders then we're not slowing down the pipeline by being in the second set)
