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.

NFSSTAT(1)						    BSD General Commands Manual 						NFSSTAT(1)

NAME
nfsstat -- display NFS statistics SYNOPSIS
nfsstat [-cemoszW] [-M core] [-N system] [-w wait] DESCRIPTION
The nfsstat command displays statistics kept about NFS client and server activity. For the NFSv4 server, the statistics are for operations within the Compound RPCs and not the count of RPCs. If you wish to compare RPC counts between NFSv3 and NFSv4, you must use statistics in the client(s). The options are as follows: -c Only display client side statistics. -e Report the extra statistics collected by the new NFS client and server for NFSv4. This option is incompatible with -o. -M Extract values associated with the name list from the specified core instead of the default /dev/kmem. -m Report the mount options for all new NFS client mounts. This option overrides all others and nfsstat will exit after completing the report. This option is only supported by the new NFS client. -N Extract the name list from the specified system instead of the default /boot/kernel/kernel. -o Report statistics for the old NFS client and/or server. Without this option statistics for the new NFS client and/or server will be reported. -s Only display server side statistics. -W Use wide format with interval short summary. This option is especially useful when combined with -c or -s and a time delay. -w Display a shorter summary of NFS activity for both the client and server at wait second intervals. -z Reset statistics after displaying them.
