  1. If read dominates, add RAM on the clients to cache more of the file systems and reduce read operations.
  2. If write dominates, make sure the clients are using noatime,nodiratime to avoid updating access times. …
  3. If getattr dominates, tune the attribute caches.

If access to remote files seems unusually slow, ensure that access time is not being inhibited by a runaway daemon, a bad tty line, or a similar problem. Use the nfsstat command to gather information about your network connections. To set MTU size, use the SMIT fast path, smit chif .

Which is better SMB or NFS?

NFS offers better performance and is unbeatable if the files are medium-sized or small. For larger files, the timings of both methods are almost the same. In the case of sequential read, the performance of NFS and SMB are almost the same when using plain text. However, with encryption, NFS is better than SMB.

What is NFS v4?
