目录 批量网络流量性能测试 TCP_STREAM测试UDP_STREAM 测试请求/应答网络流量测试 TCP_RR TCP_CRR Netperf 是一个网络性能测试工具它可以测试网络协议栈的性能例如TCP和UDP协议。Netperf可以测量网络吞吐量、延迟和CPU利用率等指标。它是一个开源工具可在多种操作系统上运行包括Linux、Windows和Mac OS X等。
Netperf支持多种常见的网络测试模式包括TCP_STREAM、UDP_STREAM、TCP_MAERTS和UDP_RR等。用户可以使用Netperf来测试本地和远程网络的性能以评估网络基础设施的性能和可靠性。
批量网络流量性能测试
根据使用传输协议的不同批量数据传输又分为TCP批量传输和UDP批量传输。 服务端 服务端启动服务执行
eddyeddy:~$ netserver
Unable to start netserver with IN(6)ADDR_ANY port 12865 and family AF_UNSPEC默认情况下 netserver 开启端口号为 12865可以通过以下命令指定服务端口如果服务端指定端口则客户端也需要指定服务器端口

Use hexadecimal.-Z passphrase Set and pass to netserver a passphraseFor 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.查看netserver帮助

Netperf缺省情况下进行TCP批量传输即-t TCP_STREAM用来测试进行TCP批量传输时的网络性能。
测试过程中netperf向netserver发送批量的TCP数据分组以确定数据传输过程中的吞吐量。

UDP_STREAM用来测试进行UDP批量传输时的网络性能。
测试UDP的网络性能时测试分组的大小不得大于socket的发送与接收缓冲大小否则netperf会报出错提示。

TCP_RR
TCP_RR 方式的测试对象是多次 TCP request 和 response 的交易过程但是它们发生在同一个 TCP 连接中这种模式常常出现在数据库应用中。数据库的 client 程序与 server 程序建立一个 TCP 连接以后就在这个连接中传送数据库的多次交易过程。
