内网两台linux的设备之间传大约100G的文件，以前的土法是win10上分别打开两台机的 SMB目录，然后复制黏贴。
得到的网速大约是 50M/s左右。

那么我在想，是不是因为经过我win中间转发上下行让速度折半了呢？
如果让两台linux直接对传，是不是速度会更接近千兆局域网的100M/s 理想速度呢？

弯路

先试了两个方案 scp 和 sftp ，结论是两个都挺慢的，只有 6M/s左右的速度，我还以为我的眼睛看错了。

SFTP

root@omv:~# sftp root@192.168.0.39

SCP

其他 rsync, nc, dd, gzip数据流压缩之类的就没有再深入研究了。因为两台都是 arm的机器性能不会太强，看上面的数据内容也知道是电影不是文本 压缩不会有太大的帮助。

smb

原本在win下都有50M/s的速度，那linux试试之间直接也走smb看看效果

安装smbclient

apt install smbclient -y

root@omv:~# smbclient -uflamen //192.168.0.39/share/
Enter root's password: 
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 3.6.3-31a.osstech]
smb: \> 
smb: \> cd new
smb: \new\> pwd
Current directory is \\192.168.0.39\share\new\
smb: \new\> lcd /home/movie/test/

尝试下载，不支持通配符 * 报错

smb: \new\> mget *
NT_STATUS_NO_SUCH_FILE listing \new\*
smb: \new\> cd ..
smb: \> mget new
NT_STATUS_NO_SUCH_FILE listing \new

要加多两个命令 prompt 和 recurse

smb: \> prompt
smb: \> recurse
smb: \> mget new

结论是..并没有快，哈哈哈哈。55M/s左右只快了一点点。

瞎折腾 =___=||
