Hello everyone!
  =20
  I am trying to understand the output of nfsstat to better understand an=
d tweak NFS performance for our machines.=20
  =20
  Following is the output from our Solaris 9, NFSv3 running server:
  =20
  I am concerned about the "badcalls" for "Server nfs" output, is this no=
rmal or something is wrong. We have some of our clients mounting the expo=
rted File system with rsize & wsize =3D 32K,  Could this be the problem, =
is there a way to narrow it down?
  =20
  Any feedback is greatly appreciated!
  =20
  ~thanks ~al
