Current list of things to fix/add to iperf3 - readd -Z option (linux tcp congestion control algoritm) - readd flag to set IP_TOS (-S) - add debug options and extend verbose mode - add more iperf API support and documentation - look for 'XXX' in code and address - better packaging/makefile, README, LICENCE, etc files - document and verify the 'state machine'. Is it an error to send messages in the wrong order? - e.g.: what is "STREAM_RUNNING" vs "TEST_RUNNING"?? - add human readable vs machine readable output mode (my idea on this is that "human readable" = compatable with old iperf, and that "machine readable is all name=value pairs -blt ) - more testing - add daemon mode (-D) - see issue tracker for other wish list items http://code.google.com/p/iperf/issues/list
