Netperf是一种网络性能的测量工具，主要针对基于TCP或UDP的传输。Netperf根据应用的不同，可以进行不同模式的网络性能测试，即批量数据传输（bulk data transfer）模式和请求/应答（request/reponse）模式。
Netperf工具以client/server方式工作。server端是netserver,用来侦听来自client端的连接,client端是netperf,用来向server发起网络测试.在client与server之间,首先建立一个控制连接,传递有关测试配置的信息,以及测试的结果:在控制连接建立并传递了测试配置信息以后，client与server之间会再建立一个测试连接,进行来回传递特殊的流量模式,以测试网络的性能

[root@xiesshavip001 ~]#[root@xiesshavip001 ~]# netperf --help
netperf: invalid option -- ‘-‘
Usage: netperf [global options] -- [test options]
Global options:
-a send,recv Set the local send,recv buffer alignment
-A send,recv Set the remote send,recv buffer alignment
-B brandstr Specify a string to be emitted with brief output
-c [cpu_rate] Report local CPU usage
-C [cpu_rate] Report remote CPU usage
-d Increase debugging output
-D time,[units] * Display interim results at least every time interval
using units as the initial guess for units per second
A negative value for time will make heavy use of the
system‘s timestamping functionality
-f G|M|K|g|m|k Set the output units
-F lfill[,rfill]* Pre-fill buffers with data from specified file
-h Display this text
-H name|ip,fam * Specify the target machine and/or local ip and family
-i max,min Specify the max and min number of iterations (15,1)
-I lvl[,intvl] Specify confidence level (95 or 99) (99)
and confidence interval in percentage (10)
-j Keep additional timing statistics
-l testlen Specify test duration (>0 secs) (<0 bytes|trans)
-L name|ip,fam * Specify the local ip|name and address family
-o send,recv Set the local send,recv buffer offsets
-O send,recv Set the remote send,recv buffer offset
-n numcpu Set the number of processors for CPU util
-N Establish no control connection, do ‘send‘ side only
-p port,lport* Specify netserver port number and/or local port
-P 0|1 Don‘t/Do display test headers
-r Allow confidence to be hit on result only
-s seconds Wait seconds between test setup and test start
-S Set SO_KEEPALIVE on the data connection
-t testname Specify test to perform
-T lcpu,rcpu Request netperf/netserver be bound to local/remote cpu
-v verbosity Specify the verbosity level
-W send,recv Set the number of send,recv buffers
-v level Set the verbosity level (default 1, min 0)
-V Display the netperf version and exit
-y local,remote Set the socket priority
-Y local,remote Set the IP_TOS. Use hexadecimal.
-Z passphrase Set and pass to netserver a passphrase
For those options taking two parms, at least one must be specified;
specifying one value without a comma will set both parms to that
value, specifying a value with a leading comma will set just the second
parm, a value with a trailing comma will set just the first. To set
each parm to unique values, specify both and separate them with a
comma.
* For these options taking two parms, specifying one value with no comma
will only set the first parms and will leave the second at the default
value. To set the second value it must be preceded with a comma or be a
comma-separated pair. This is to retain previous netperf behaviour.
