将 mycloud 通过 samba 和 nfs 挂载到一台 centos7 到机器上，用 dd 测速，传输速度相差一倍，测速多次也一样。samba3 明显快，这是 3 做了改动么？另复制进去的文件权限改变了。按照查询的进行更改（添加 map 啥的）无效。

查询好像和下面 4 个设置相关，正在测试。。。有老哥能给点提醒么？想实现点挂载后和普通硬盘一样，权限不变，性能插不了多少。

create mask = 0777 
directory mask  = 0777 
force create mode = 0777 
force directory mode = 0777

挂载

//192.168.3.24/data     2.7T  122G  2.6T   5% /mnt/data
192.168.3.24:/nfs/data  2.7T   94G  2.6T   4% /root/data

dd 测速

samba

1+0 records in
1+0 records out
1073741824 bytes (1.1 GB) copied, 12.5367 s, 85.6 MB/s

nfs
