Yes, I actually increased its ccache size on July 6th but only from 5 GB
to 20 GB because the machine running that builder is also a development
box. Looking at the build times graph it looks like it helped a bit but
not a lot.

I now increased the size again to 40 GB. I'll monitor to see if there's
an impact.

Does adding a “depends_on_projects” argument help reduce the number of
notified people? Or is there something else that could/should be done
about that?

Thank you for the suggestion, I see that many builders running on Linaro
workers don't have it. I'll prepare a patch to add “depends_on_projects”
arguments to them.

Though specifically for clang-aarch64-sve-vla-2stage IIUC its value
would be ["llvm", "mlir", "clang", "flang"] (since it's meant to test
flang as well), so perhaps it wouldn't change much in practice?
