Huawei H13-629 Exam - Topic 3 Question 87 Discussion

A Huawei 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) 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. and B) Async, allowing asynchronous data write, synchronous write requirements. NFS server must brush each data into the hard disk before it can return success delay higher. and C) 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.
D) Nolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

Option B seems risky. Synchronous writes can slow things down too much.

Just to clarify, A) is 1M for most setups, but check your system limits!

Wait, I thought Nolock was only for specific use cases?

I vaguely recall that using nolock can help with performance in shared environments, but I’m not entirely clear on how it affects file integrity.

I practiced with the noatime option before, and it makes sense to use it if we don't need access times. It should help reduce overhead.

I think the async option is important for improving write performance, but I’m a bit confused about when synchronous writes are actually necessary.

I remember that rsize and wsize can definitely impact performance, but I'm not sure if 1M is the maximum for all Linux systems.
