Are those stats from running the jobs in a arm32v7 container with qemu on a arm64v8 OS, or does the AWS hypervisor allow for booting into a arm32v7 guest OS to avoid qemu when building with docker?
A cool (I think feature) of the images used by the buildfarm that bundle binaries from qemu-user-static is that they rely on the host kernel's binfmt to invoke non-native binaries with qemu. So on native platforms the same image will run without qemu and, in fact, the bundled qemu binary is AMD64 native and so it would fail to run if invoked by binfmt.
But the python script was running directly on the host so the docker images weren't involved in that runtime measurement yet.
