I'm assuming that you'd run many benchmarks, not just "Hello world". Each one will run for some number of cycles, to make sure that you have a good mean from each run.
So it's expensive b/c it consumes CPU and time on shared systems, and those cost money... so I think a service like this could potentially cost significantly more to operate than say travis-ci.
