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!

dfshares_nfs
dfshares_nfs(1M) System Administration Commands dfshares_nfs(1M)
NAME
dfshares_nfs - list available NFS resources from remote systems
SYNOPSIS
dfshares [ -F nfs] [-h] [server...]
DESCRIPTION
dfshares provides information about resources available to the host through NFS. The -F flag may be omitted if NFS is the first file sys-
tem type listed in the file /etc/dfs/fstypes.
The query may be restricted to the output of resources available from one or more servers.
dfshares without arguments displays all resources shared on the local system, regardless of file system type.
Specifying server displays information about the resources shared by each server. Server can be any system on the network. If no server
is specified, then server is assumed to be the local system.
The output of dfshares consists of an optional header line (suppressed with the -h flag) followed by a list of lines containing whitespace-
separated fields. For each resource, the fields are:
resource server access transport
where
resource Specifies the resource name that must be given to the mount(1M) command.
server Specifies the system that is making the resource available.
access Specifies the access permissions granted to the client systems; however, dfshares cannot determine this information
for an NFS resource and populates the field with a hyphen (-).
transport Specifies the transport provider over which the resource is shared; however, dfshares cannot determine this information
for an NFS resource and populates the field with a hyphen (-).
A field may be null. Each null field is indicated by a hyphen (-) unless the remainder of the fields on the line are also null; in which
case, the hyphen may be omitted.
OPTIONS
-F nfs Specify the NFS file system type
-h Suppress header line in output.
FILES
/etc/dfs/fstypes
