That's perfectly correct and not odd at all: the nagle algorithm tries to
improve the overall network load by not sending too many small packets. What
you need is the opposite: low latency. It's perfectly normal on every TCP/IP
platform to disable the nagle algorithm for such applications. E.g. remote
shells would not work well with nagle turned on as that would introduce a
minimum delay of 200ms for every keystroke.
