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

Help on this will be greatful
Thanks

Use NFS over TCP and set rsize,wsize = 32K .It will definitely resolve ur
problem.
