Thanks to your reply and waiting your update.
Actually, I didn't mean C# have api that can improve tcp performance
intelligently but there must exist some magic behind that I don't know.
I guess if java have access to OS level tcp settings, it may possible to
fine tune tcp performance dynamically and programmically. What I have
observed is a very real use case and I can confirmed the transportation
speed is really improved without modifying my java client server or adjust
any windows registry.
before:
<remote server host> -- 2M lease line -- <java client server> -- local lan
-- <java applet on browser>
middle ware plugged in:
<remote server host> -- 2M lease line -- <c# middle ware> -- localhost --
<java client server> -- local lan -- <java applet on browser>
