sorry guys if above content is not clear.

Actually what I want to know is what is the nfsd process running under root. I guess it is something related to OS nfs processors.

But should it take so much of the processor resource , and why the nice is getting 28% of CPU.

Is these normal .... ?

rpc.nfsd(8)						      System Manager's Manual						       rpc.nfsd(8)

NAME

       rpc.nfsd - NFS server process

SYNOPSIS

       /usr/sbin/rpc.nfsd [-p port] nproc

DESCRIPTION

       The  rpc.nfsd program implements the user level part of the NFS service. The main functionality is handled by the nfsd.o kernel module; the
       user space program merely starts the specified number of kernel threads.

       The rpc.mountd server provides an ancially service needed to satisfy mount requests by NFS clients.

OPTIONS

       -p port
	      specify a diferent port to listen on for NFS requests. By default, rpc.nfsd will listen on port 2049.

       nproc  specify the number of NFS server threads. By default, just one thread is started. However, for optimum performance  several  threads
	      should be used. The actual figure depends on the number of and the work load created by the NFS clients, but a useful starting point
	      is 8 threads. Effects of modifying that number can be checked using the nfsstat(8) program.

       rpc.mountd(8), exportfs(8), rpc.rquotad(8), nfsstat(8).
