The problem is not bandwidth. It's latency (which pretty much kills
sync performance). Async aren't affected by latency, which is why I
prefer using async wherever possible. Even at the cost of live

Again, if you've tested that it fits your requirement, or your
workload is extremely low, then you should be fine.
