i want send bit through ethernet port reduce speed , have below question:

1- affect in speed? how it? there no such thing in msdn website.

https://msdn.microsoft.com/en-us/library/system.net.sockets.socket%28v=vs.110%29.aspx

2- better use many windows application many send byte ?

along each message send, header included, containing instance destination address. without information, message never arrive @ destination.

a typical ipv4 header 20 bytes. if possible, 8 bits not 700% more data 1 bit, 33% more.

since each message includes such header, should try include as possible data reduce number of messages need send.

if answer not help, might want include ultimate goal, trying achieve?
