1.       About netperf
Netperf is a benchmark that can be use to measure various aspect of networking performance. The primary foci are bulk (aka unidirectional) data transfer and request/response performance using either TCP or UDP and the Berkeley Sockets interface. As of this writing, the tests available either unconditionally or conditionally include:
TCP and UDP unidirectional transfer and request/response over IPv4 and IPv6 using the Sockets interface.
TCP and UDP unidirectional transfer and request/response over IPv4 using the XTI interface.
Link-level unidirectional transfer and request/response using the DLPI interface.
Unix domain sockets
SCTP unidirectional transfer and request/response over IPv4 and IPv6 using the sockets interface.

2.       Download netperf
google “netperf-2.4.0.tar.gz” on the Internet.
3.       Cross compile netperf-2.4.0.tar.gz
./configure CC=arm-linux-gcc --includedir=/opt/montavista/pro/devkit/arm/v5t_le/include/ --libdir=/opt/montavista/pro/devkit/arm/v5t_le/lib/ --host=arm-linux --prefix=/work/nfs_filesystem/target/work/tools/netperf_install

Error:
checking whether setpgrp takes no argument... configure: error: cannot check setpgrp when cross compiling

Solve it:
vim configure
line: 6091   ignore  exit(1)
      
/configure CC=arm-linux-gcc --includedir=/opt/montavista/pro/devkit/arm/v5t_le/include/ --libdir=/opt/montavista/pro/devkit/arm/v5t_le/lib/ --host=arm-linux --prefix=/work/nfs_filesystem/target/work/tools/netperf_install
make
make install

then, netperf and netserver are installed under directory “/work/tools/netperf_install” on the target filesystem.

4.       Profiling networking performance.

4.2 without lookback
Subsequently, profile the performace of transmission through TCP, the following command will transmit TCP packages to remotehost 192.168.167.131 for 10 seconds.
./netperf -H 192.168.167.131
TCP STREAM TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.167.131 (192.168.167.131) port 0 AF_INET

Make measurement for UDP Stream transmition performance
./netperf -H 192.168.167.131 -t UDP_STREAM -- -m 1024
UDP UNIDIRECTIONAL SEND TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.167.131 (192.168.167.131) port 0 AF_INET

110592           10.01       11514              9.42

note:
netperf tool must be setup on the host:192.168.167.131 in advace.
