NFS performance

Hi,

In our environment (HP-UX B.11.11) we mainly use NFS v3 resources as the storage solution for our application. It worked fine, however we have recently noticed big I/O performance degradation that affected the application.

Is there any command or utility that can help us measure I/O efficiency for NFS mounted storage? I am the most interested in read/write rate (bytes per second) and call response time. Maybe do you know other useful methods for NFS performance measure?

Kind regards
Pit

MOUNT.NFS(8)						      System Manager's Manual						      MOUNT.NFS(8)

NAME
mount.nfs, mount.nfs4 - mount a Network File System SYNOPSIS
mount.nfs remotetarget dir [-rvVwfnsh ] [-o options] DESCRIPTION
mount.nfs is a part of nfs(5) utilities package, which provides NFS client functionality. mount.nfs is meant to be used by the mount(8) command for mounting NFS shares. This subcommand, however, can also be used as a standalone command with limited functionality. mount.nfs4 is used for mounting NFSv4 file system, while mount.nfs is used to mount NFS file systems versions 3 or 2. remotetarget is a server share usually in the form of servername:/path/to/share. dir is the directory on which the file system is to be mounted. OPTIONS
-r Mount file system readonly. -v Be verbose. -V Print version. -w Mount file system read-write. -f Fake mount. Don't actually call the mount system call. -n Do not update /etc/mtab. By default, an entry is created in /etc/mtab for every mounted file system. Use this option to skip making an entry. -s Tolerate sloppy mount options rather than fail. -h Print help message. nfsoptions Refer to nfs(5) or mount(8) manual pages. NOTE
For further information please refer nfs(5) and mount(8) manual pages. FILES
