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

nfs

~ # dd if=/dev/zero of=/root/data/test2.img bs=1G count=1 oflag=dsync 1+0 records in 1+0 records out 1073741824 bytes (1.1 GB) copied, 24.5374 s, 43.8 MB/s
