-> iperf3 "-h"
Usage: iperf3 [-s|-c host] [options]
       iperf3 [-h|--help] [-v|--version]
Server or Client:
  -p, --port      #         server port to listen on/connect to
  -f, --format   [kmgtKMGT] format to report: Kbits, Mbits, Gbits, Tbits
  -i, --interval  #         seconds between periodic throughput reports
  -I, --pidfile file        write PID file
  -F, --file name           xmit/recv the specified file
  -B, --bind      <host>    bind to the interface associated with the address <host>
  -V, --verbose             more detailed output
  -J, --json                output in JSON format
  --logfile f               send output to a log file
  --forceflush              force flushing output at every interval
  --timestamps<=format>     emit a timestamp at the start of each output line (optional "=" and format string as per strftime(3))
  --rcv-timeout #           idle timeout for receiving data (default 120000 ms)
  -d, --debug[=#]           emit debugging output (optional optional "=" and debug level: 1-4. Default is 4 - all messages)
  -v, --version             show version information and quit
  -h, --help                show this message and quit
Server specific:
  -s, --server              run in server mode
  -D, --daemon              run the server as a daemon
  -1, --one-off             handle one client connection then exit
  --server-bitrate-limit #[KMG][/#]   server's total bit rate limit (default 0 = no limit) (optional slash and number of secs interval for averaging total data rate.  Default is 5 seconds)
  --idle-timeout #          restart idle server after # seconds in case it got stuck (default - no timeout)
Client specific:
  -c, --client <host>[%<dev>] run in client mode, connecting to <host> (option <dev> equivalent to `--bind-dev <dev>`)
  -u, --udp                 use UDP rather than TCP
  --connect-timeout #       timeout for control connection setup (ms)
  -b, --bitrate #[KMG][/#]  target bitrate in bits/sec (0 for unlimited) (default 1 Mbit/sec for UDP, unlimited for TCP) (optional slash and packet count for burst mode)
  --pacing-timer #[KMG]     set the timing for pacing, in microseconds (default 1000)
  -t, --time      #         time in seconds to transmit for (default 10 secs)
  -n, --bytes     #[KMG]    number of bytes to transmit (instead of -t)
  -k, --blockcount #[KMG]   number of blocks (packets) to transmit (instead of -t or -n)
  -l, --length    #[KMG]    length of buffer to read or write (default 128 KB for TCP, dynamic or 1460 for UDP)
  --cport         <port>    bind to a specific client port (TCP and UDP, default: ephemeral port)
  -P, --parallel  #         number of parallel client streams to run
  -R, --reverse             run in reverse mode (server sends, client receives)
  --bidir                   run in bidirectional mode. Client and server send and receive data.
  -w, --window    #[KMG]    set send/receive socket buffer sizes (indirectly sets TCP window size)
  -M, --set-mss   #         set TCP/SCTP maximum segment size (MTU - 40 bytes)
  -N, --no-delay            set TCP/SCTP no delay, disabling Nagle's Algorithm
  -4, --version4            only use IPv4
  -6, --version6            only use IPv6
  -S, --tos N               set the IP type of service, 0-255. The usual prefixes for octal and hex can be used, i.e. 52, 064 and 0x34 all specify the same value.
  --dscp N or --dscp val    set the IP dscp value, either 0-63 or symbolic. Numeric values can be specified in decimal, octal and hex (see --tos above).
  -L, --flowlabel N         set the IPv6 flow label (only supported on Linux)
  -Z, --zerocopy            use a 'zero copy' method of sending data
  -O, --omit N              perform pre-test for N seconds and omit the pre-test statistics
  -T, --title str           prefix every output line with this string
  --extra-data str          data string to include in client and server JSON
  --get-server-output       get results from server
  --udp-counters-64bit      use 64-bit counters in UDP test packets
  --repeating-payload       use repeating pattern in payload, instead of randomized payload (like in iperf2)
