NFS Performance Issue
Hi,
I have a conflict.
I have 2 servers: the 1st creates an application logs and the 2nd is an empty server.

I want to export (read-only) from the 1st server by NFS the directory that contains the logs to the 2nd server.

Now, the question is:
If in the 2nd server i'm doing a lot of manipulates and reads of the logs (in the NFS from the 1st server), from which server is it takes the massive resources? (CPU, RAM)

thank you all!

On both NFS server and NFS client the NFS activity will take less resources than a native GUI application (say Firefox).

Is that possible to limit the requests from the NFS client?
I don't want the client will influence on the performance of the NFS server.

I read about the mount flag of 'rsize' but i don't have an experience with this flag.

thanks.

By reducing rsize (and wsize) (e.g. rsize=8192) in the mount option you can reduce the read (and write) speed of the NFS client. This will also reduce the disk I/O load on the NFS server. The I/O-bound CPU load will decrease a little, too.
nfsstat -m shows you the parameters of existing mounts.
The NFS mount options are described in the man pages: man nfs or man mount_nfs
In general, the effect is low. I would start with the default mount options.
