通过Thunderbolt缓慢上载，可以正常下载

问题描述 投票：-1回答：1

我对Thunderbolt和以下LAN配置有问题：

Mac-（1）-NAS-（2）-网关

  1. Thunderbolt作为网络，IP路由，无NAT
  2. 以太网，IP路由，无NAT

NAS（Debian Buster，5.4.0-0.bpo.4-amd64）具有以太网（eth）和雷电（thu）。 Thunderbolt用于Mac和NAS之间的联网因为它比以太网快得多。

有效的方法：

  • 数据Mac«-thu-»NAS快速传输。
  • 数据Mac«-eth-»NAS快速传输（实验）。
  • 数据NAS«-eth-»网关快速传输。
  • 数据网关 -eth-»NAS -eth-»Mac （无NAT）快速传输。
  • 数据Mac -eth-»NAS -eth-»网关 （无NAT）快速传输。
  • 数据网关 -eth-»NAS -thu-»Mac （无NAT）快速传输。

什么不起作用：

  • 数据Mac -thu-»NAS -eth-»网关 （无NAT，仅IP路由）传输慢 （〜1Mbps ）。

这意味着从Mac通过ethernet通过NAS然后通过以太网到网关的方式为[[OK，但是从Mac通过thunderbolt通过NAS然后通过以太网到网关的方式是slow，约1 Mbps Mac和NAS之间通过雷电在没有其他跃点的情况下进行的同时连接可以快速运行（（AFP传输，双向）。

此外，直接从Mac到Internet的基于IPSec的VPN L2TP甚至可以快速运行通过雷电！这意味着UDP传输也很快。

似乎问题出在TCP。

NAS

发现解决方案是由于Thunderbolt实施中的TSO错误！

要修复Mac上的上传速度问题

touch /etc/sysctl.conf 

编辑/etc/sysctl.conf并放在此处：
net.inet.tcp.tso=0

然后运行sysctl -p以（重新）加载sysctl.conf
