AHuawei OceanStor 9000 is externally shared using NFS and CIFS at the moment.
You want to set some parameters to improve the performance of the NFS mounted under the Linux operating system. Which of the following description is correct?

A. Noatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.

B. Async, allowing asynchronous data write, synchronous write requirements. NFS server must brusheach data into the hard disk before it can return success delay higher.

C. Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

D. Rsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.

出題：8

In the Huawei OceanStor system, the size of the file system block is a measure of the size of the accessed file system block. The size of the block is designed according to the size of the data block. Different size of the file system block selects the corresponding file system block, according to the size of the data block. If the business scenario is the media, for large file archiving or stagger I / O backup scenarios, it is recommended to choose the default 64KB disk block size.

A. True

B. False
