setting of window size should be explicit #1

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Presently we set the window size to DEFAULT_TCP_BUFSIZE.  

This has two issues:

1. it overrides the system default implicitly
1. it may prevent the system's auto tuning from working

Instead we should set socket_snd_bufsize and socket_rcv_bufsize to zero by 
default (probably in 
iperf_defaults()).  Then when it comes time to set the socket_snd_bufsize and 
socket_rcv_bufsize 
only set it if it isn't zero.

for the present iperf the tool should use -w to set both socket_snd_bufsize and 
socket_rcv_bufsize, but in the long term we probably want options to set the 
individually.
