java - What are the factors affecting the speed in sending large amount of data in SocketChannel? -

-

can tell me specific factors affecting speed in sending large amount of data in socketchannel? example byte allocation affects speed?

the main limiting factors, in order, are:

  1. network bandwidth, mean bandwidth of slowest part of path between peers.
  2. size of socket receive buffer @ receiver. if less bandwidth-delay product of path, won't able utilize full available bandwidth.
  3. the speed @ send. contrary suggestion in comments, should send as possible @ time, , repeat rapidly can, assuming blocking mode. in non-blocking mode considerably more complex, if bandwidth utilization goal you're better off using blocking mode. you're better off using java.net rather nio too.
