I don't know the fish protocol, but the usual reason for multiple
streams going faster than a single stream is latency (e.g. time for
the other end to ack the data). You can sometimes reduce the effect of
end-to-end latency on throughput by reading and writing in larger
'chunks' - is there an option regarding that?
