I think the main objection is that it takes a huge amount of network latency to explain a > 1,500% overhead with only 2 machines.

So does gluster become faster abruptly when file sizes cross some threshold? Or are average speeds are proportional to file size? Would be good to see a wider spread of values on benchmarks of throughput vs file size for the same overall volume (like Max's data but with more intermediate values)
