It's certainly not meaningful of anything in the first place, since it only tests codegen for a sequence of floating point calculations, which is hardly a representative workload for anything. Even if it were, using an unreliable virtualised environment only introduces noise, especially in the presence of syscalls... So it's worthless even if the entire purpose was to evaluate how fast floating point sums and divisions run in a CI server x)
