The table below lists the various flags of the command.
7.4.3 ib_send_bw
ib_send_bw calculats the BW of SEND between a pair of machines. One acts as a server and the
other as a client. The server receive packets from the client and they both calculate the through-
put of the operation. The test supports features such as Bidirectional, on which they both send
and receive at the same time, change of mtu size, tx size, number of iteration, message size and
more. Using the "-a" provides results for all message sizes.
