Today I invest my time in adding a new option for "netsend": to introduce an artificial @read()@ delay in the receiver path. The new option can be enabled via:

<pre> netsend -v loudish -B 10,1 -b 250 -s SO_RCVBUF 1 tcp receive </pre>

The options states that the receiver should initial block for 10 seconds and then read 250 byte chunks with a delay of one second: @-B 10,1@. If you waive the initial delay you can also skip the coma separated list and hand over only one argument, e.g. @-b 1@. This will delay the @read()@ operation with a one second delay.
