Do you think that (outside of a few special cases) they're using anything near the network bandwidth available to them? I would expect in the 1% to 10% bandwidth utilization, on average. From my vague recollection, that's what it was at FB when I was there. They put stupid amounts of network capacity in so that the engineers rarely have to think about the capacity of the links they're using, and that if their needs grow, they're not bottlenecked on a build out. To answer the original question, it's complicated. I have a weird client where freebsd gets 450 MiB/s, and Linux gets 85 with the default congestion control algorithm. Changing the congestion control algorithm can get me between 1.7 MiB/s and 470 MiB/s. So, better performance... Under what circumstances?
