The handoff between tstun.Wrap's Read and poll methods is one of the per-packet hotspots. It shows up in pprof. Making outbound buffered increases throughput. It is hard to measure exactly how much, because the numbers are highly variable, but I'd estimate it at about 1%, using the best observed max throughput across three runs.
