I have a question about the -s option. In the manual of revision 2.1 it
says that this will set the local send and receive buffer sizes to the
value specified. The -S option will do the same for the remote system.
What kind of buffer is actually meant...:
1) Is this just a buffer of the system's input and output functions?
2) Or does this parameter set the maximum window size of TCP, and can
reach up to the max. CWND of 64 kBytes which is defined in the OS?
In both cases: is it correct that it is counted in bytes?
BTW: I am sending TCP over a satellite link with a RTT of 560 msec. Any
suggestions with which params it's mostly worth to play around?
Thanks for any help!
