群晖最近更新了 SMB Server，官方支持了 SMB 多通道，原先只能通过修改 SMB config 文件启用，更新系统还会失效，不是很方便。这对于有两个 1GbE 口的群晖还是比较实用的。

## 准备工作
### 硬件配置
如果你的环境是千兆，那你的 PC 需要有至少两个网口，然后按照下图连接网线

如果环境是 2.5G 或者 10G，电脑就不需要插两根网线了

当然如果有多个交换机，下面这样也是可以的，我就是这么用的

### 软件配置
群晖在控制面板 - SMB选项卡 - 高级设置 - 其他选项卡 - 启用SMB3多通道
![](https://img.mitsea.com/blog/posts/2023/01/%E7%BE%A4%E6%99%96%20SMB%20%E5%A4%9A%E9%80%9A%E9%81%93%E5%AE%98%E6%96%B9%E6%9B%B4%E6%96%B0%E8%A7%82%E5%AF%9FUntitled%204.png?x-oss-process=style/ImageCompress)
Windows 应该不用设置，默认是开启的。可以通过 `Get-SmbServerConfiguration` 在 PowerShell 里检查一下是否开启。如果没开启，可以通过 `Set-SmbServerConfiguration -EnableMultiChannel 1` 开启。
## 测试
### 上传
大概 210MB/s 左右
![](https://img.mitsea.com/blog/posts/2023/01/%E7%BE%A4%E6%99%96%20SMB%20%E5%A4%9A%E9%80%9A%E9%81%93%E5%AE%98%E6%96%B9%E6%9B%B4%E6%96%B0%E8%A7%82%E5%AF%9FUntitled%205.png?x-oss-process=style/ImageCompress)
### 下载
大概 210MB/s 左右
![](https://img.mitsea.com/blog/posts/2023/01/%E7%BE%A4%E6%99%96%20SMB%20%E5%A4%9A%E9%80%9A%E9%81%93%E5%AE%98%E6%96%B9%E6%9B%B4%E6%96%B0%E8%A7%82%E5%AF%9FUntitled%206.png?x-oss-process=style/ImageCompress)
### 大量中等文件混合下载
有正常的波动，总体比 1Gbps 快不少

## 其他
细心的应该观察到了，我下载时使用的是 Directory Opus，上传时使用的是自带 Explorer。这是因为如果下载使用 Explorer，上传使用 DO，速度都只有千兆。

可能是目前还有兼容性问题和bug，不过感觉问题不大。
