odroid c2 / armbian 쓰는데 termiantor 가 기본 터미널이라 쓸데없이(!) 폰트만 커서 마음에 안들어
변경하는법 찾음. 단축키로는 x-terminal-emulator가 실행되고
이게 연결된 프로그램으로 넘겨주는 듯 한데, gnome-terminal이 간결하고 짱이지 ㅋ
$ sudo update-alternatives --config x-terminal-emulator 대체 항목 x-terminal-emulator에 대해 (/usr/bin/x-terminal-emulator 제공) 2개 선택이 있습니다.

$ man iperf3 -A, --affinity n/n,m Set the CPU affinity, if possible (Linux, FreeBSD, and Windows only). On both the client and server you can set the local affinity by using the n form of this argument (where n is a CPU number). In addition, on the client side you can override the server's affinity for just that one test, using the n,m form of argument. Note that when using this feature, a process will only be bound to a single CPU (as opposed to a set containing potentialy mul‐ tiple CPUs).
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 -F, --file name xmit/recv the specified file -A, --affinity n/n,m set CPU affinity -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 (using optional format string as per strftime(3)) -d, --debug emit debugging output -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 -I, --pidfile file write PID file -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) --rsa-private-key-path path to the RSA private key used to decrypt authentication credentials --authorized-users-path path to the configuration file containing user credentials Client specific: -c, --client <host> run in client mode, connecting to <host> --sctp use SCTP rather than TCP -X, --xbind <name> bind SCTP association to links --nstreams # number of SCTP streams -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) --fq-rate #[KMG] enable fair-queuing based socket pacing in bits/sec (Linux only) -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.

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 omit the first n seconds -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) --username username for authentication --rsa-public-key-path path to the RSA public key used to encrypt authentication credentials

Set the CPU affinity for the sender (-A 2) or the sender, receiver (-A 2,3), where the core numbering starts at 0. This has the same effect as running numactl -C 4 iperf3.
