Plan to add for the next release:
|
||||
-D, --daemon run the server as a daemon

|
||||
Not planning to support. If you really miss these options, please submit a request in the issue tracker
|
||||
-d, --dualtest Do a bidirectional test simultaneously
|
||||
-r, --tradeoff Do a bidirectional test individually

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
|
||||
- see issue tracker for items on the TODO list
