安裝 Iperf 網路效能測試工具
關於網路效能測試，大家應該都會想到免費又簡單操作的 Iperf ，Iperf 是由 NLANR( National Laboratory for Applied Network Research)所開發出來的工具，主要是用來量測網路的最大的 TCP / UDP 網路頻寬/效能。這套工具是在各種平台都找得到，包括在Windows、Linux、Mac OS 等常見的作業系統，連 opware ipkg 套件也有這套工具。
$ ipkg list | grep iperf
iperf - 2.0.4-1 - A tool for measuring TCP and UDP bandwidth performance.
果然有，這真是太神奇了!! 那就嘗試把它安裝上去吧
$ ipkg install iperf
Installing iperf (2.0.4-1) to /opt/...
Downloading http://ipkg.nslu2-linux.org/feeds/optware/oleg/cross/stable/iperf_2.0.4-1_mipsel.ipk
Configuring iperf
Successfully terminated.
安裝完成，看一下操作說明，操作方式和在windows下操作方式大同小異。
$ iperf --help
Usage: iperf [-s|-c host] [options]
iperf [-h|--help] [-v|--version]
Client/Server:
-f, --format [kmKM] format to report: Kbits, Mbits, KBytes, MBytes
-i, --interval # seconds between periodic bandwidth reports
-l, --len #[KM] length of buffer to read or write (default 8 KB)
-m, --print_mss print TCP maximum segment size (MTU - TCP/IP header)
-o, --output output the report or error message to this specified file
-p, --port # server port to listen on/connect to
-u, --udp use UDP rather than TCP
-w, --window #[KM] TCP window size (socket buffer size)
-B, --bind bind to , an interface or multicast address
-C, --compatibility for use with older versions does not sent extra msgs
-M, --mss # set TCP maximum segment size (MTU - 40 bytes)
-N, --nodelay set TCP no delay, disabling Nagle's Algorithm
-V, --IPv6Version Set the domain to IPv6
Server specific:
-s, --server run in server mode
-U, --single_udp run in single threaded UDP mode
-D, --daemon run the server as a daemon
Client specific:
-b, --bandwidth #[KM] for UDP, bandwidth to send at in bits/sec
(default 1 Mbit/sec, implies -u)
-c, --client run in client mode, connecting to
-d, --dualtest Do a bidirectional test simultaneously
-n, --num #[KM] number of bytes to transmit (instead of -t)
-r, --tradeoff Do a bidirectional test individually
-t, --time # time in seconds to transmit for (default 10 secs)
-F, --fileinput input the data to be transmitted from a file
-I, --stdin input the data to be transmitted from stdin
-L, --listenport # port to recieve bidirectional tests back on
-P, --parallel # number of parallel client threads to run
-T, --ttl # time-to-live, for multicast (default 1)
-Z, --linux-congestion set TCP congestion control algorithm (Linux only)
Miscellaneous:
-x, --reportexclude [CDMSV] exclude C(connection) D(data) M(multicast) S(settings) V(server) reports
-y, --reportstyle C report as a Comma-Separated Values
-h, --help print this message and quit
-v, --version print version information and quit
[KM] Indicates options that support a K or M suffix for kilo- or mega-
The TCP window size option can be set by the environment variable
TCP_WINDOW_SIZE. Most other options can be set by an environment variable
IPERF_＜long option name>, such as IPERF_BANDWIDTH.
