openvpn 聚合 iperf3 测速正常，但是 speedtest-cli 依旧很慢

因为出国线路拥堵，用 openvpn 单线转发性能捉急，楼主调研发现了 openvpn bonding 这个玩意，可以做到多线程多链路转发。
在参考了 github 上 onemarcfifty/openvpn-bonding 这个项目后也算折腾起来了，使用 bond 模式 0 和 2 都可以做到网络提速，通过 iperf3 和服务端连接多线程测速，可以达到 50 多 mbps 的下行速度，可是用 speedtest 进行测速就只有 4mbps 。
有热心的 v2er 知道原因吗。。。 help

speedtest-cli 测速
这个命令行测速工具应该是多线程测速，通过浏览器访问 speedtest 也是这个速度

测国内节点

whyorwhynot OP @tia 通过 vpn 测 speedtest 国内节点？选择了一个靠近本地的节点，浙江宁波移动， 延迟 440ms Download 2.25Mbps，Upload 1.41 Mbps

你确定 speedtest-cli 是多线程测速？ speedtest-cli -h 看看有没有更多的 option 可以打开更多的 log, 一般是-vv(两个 vv 看下详细的 log,或者用 tcpdump 抓下包看看）

试试 speedtest 官方的 cli https://www.speedtest.net/zh-Hans/apps/cli
|
|

whyorwhynot OP @huangya 是多线程的，看了一下代码，默认 8 线程，有一个 single 参数可以修改为单线程测速，测出来是多线程速度的差不多 1/8 (0.52 Mbit/s)
|

whyorwhynot OP @JimmyTinsley 官方的 speedtest 默认线程数比 speedtest-cli 少了一半，是 4 个连接，测出来 download 2.3mbps 。。

内网中转鸡场，IPLC 流量转发，哪个不比你折腾的这玩艺要强
|
|

whyorwhynot OP @dsnap5 机场之类的也在用，流量有限，带宽给他们占满了也不好。折腾这个主要是因为用自己的 vps 可以无限流量，中转一下长期挂着 BT 下载，也有些图拉丁思想。这个 bonding 可能效果就是这么差吧。。。。逃

换成 speedtest-cli 仓库里的 speedtest-cli.py 即可解

@whyorwhynot 讲真，你这种如果不走一些特殊的优化的线路，跟着公网挤，用啥都一样的。

openvpn 的单线程性能瓶颈应该是在跑大流量，200mbps 以上一个核心的 CPU 占用会飙升到 90%之后回落，伴随传输掉速。
如果你公网路线垃圾的话，多线程也救不了你。 |

是 openVPN udp ？ udp 的话，换 wireguard 试试。tcp 的话，也可以试试 pptp bonding 。 公网线路差的话什么都救不了你。

whyorwhynot OP @luyunpsyduck @lin559671 公网线路垃圾。其实这 bonding 的多个线路还是走的 cloudflare cdn 通过 v2ray 任意门转发出来的
