Hi,

I have Redhat linux 7.2 and NFS V3 working on it. it puts too much load on network which slows down all network operations.
Also I am running NFS on Solaris 7. I just want to know the who is cause the problem.

both side NFS working on UDP.

  a.. the version of nfs-utils Iam  are using (nfs-utils-0.3.1-13.7.2.1)

  b.. the version of the kernel and any non-stock applied kernels. is (2.4.7-10)

  c.. the distribution of linux you are using (REDHAT )

  d.. the version(s) of other operating systems involved. ( Linux 7.2)

It is also useful to know the networking configuration connecting the hosts ( cat 5 with 10/100 switch network).

Linux NFS server.


  a.. the output of rpcinfo -p localhost run on the server out put is
