华为云两台机器对端网速测试
背景
最近用户反映网站卡顿，于是查找原因
问题
华为云上监控事件显示，带宽超出严重。这边着手测试一下。
解决
1.首先把超宽最多的机器HRT-HD由10Mb/s增加到30Mb/s，观察是否还有频繁超宽的情况出现。
2.使用iperf测试一下内网和公网的两台机器网络速度如何
步骤
-
服务端和客户端都安装iperf测试工具
-
服务端机器HRT-JK（内网ip为192.168.0.123）
-
客户端机器HRT-HD（公网ip假设为1.1.1.1，内网ip为192.168.0.72），去访问服务端，公网临时使用40000端口，内网走iperf默认5001端口即可
-
服务端执行结果如下
{root@hrt-jk}# yum install iperf

Server specific:
-s, --server run in server mode
-t, --time # time in seconds to listen for new connections as well as to receive traffic (default not set)
--udp-histogram #,# enable UDP latency histogram(s) with bin width and count, e.g. 1,1000=1(ms),1000(bins)
-B, --bind <ip>[%<dev>] bind to multicast address and optional device
-H, --ssm-host <ip> set the SSM source, use with -B for (S,G)
-U, --single_udp run in single threaded UDP mode
-D, --daemon run the server as a daemon
-V, --ipv6_domain Enable IPv6 reception by setting the domain and socket to AF_INET6 (Can receive on both IPv4 and IPv6)
Client specific:
-c, --client <host> run in client mode, connecting to <host>
-d, --dualtest Do a bidirectional test simultaneously
--ipg set the the interpacket gap (milliseconds) for packets within an isochronous frame
--isochronous <frames-per-second>:<mean>,<stddev> send traffic in bursts (frames - emulate video traffic)
-n, --num #[kmgKMG] 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)
-B, --bind [<ip> | <ip:port>] bind ip (and optional port) from which to source traffic
-F, --fileinput <name> input the data to be transmitted from a file
-I, --stdin input the data to be transmitted from stdin
-L, --listenport # port to receive bidirectional tests back on
-P, --parallel # number of parallel client threads to run
-R, --reverse reverse the test (client receives, server sends)
-T, --ttl # time-to-live, for multicast (default 1)
-V, --ipv6_domain Set the domain to IPv6 (send packets over IPv6)
-X, --peer-detect perform server version detection and version exchange
-Z, --linux-congestion <algo> 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
[kmgKMG] Indicates options that support a k,m,g,K,M or G suffix
Lowercase format characters are 10^3 based and uppercase are 2^n based
(e.g. 1k = 1000, 1K = 1024, 1m = 1,000,000 and 1M = 1,048,576)
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.

结论
内网峰值5000Mb/s，平均3100Mb/s
公网峰值259Mb/s，会降低至最高30Mb/s
推荐走内网，速度快，目前给HRT-HD加了带宽到30，先观察
