so you mean you can't see sub-mounts? that is:
you mount / but /home is another filesystem and you can't see whats
on /home? in my experience this is perfectly normal operation. I believe
solaris does this as well.

I would increase the # of nfs procs on the server. for the userspace
server it looks like it is different. according to the manpage
for rpc.nfs you specify the numprocs manually in the init script:
/usr/sbin/rpc.nfsd [ -f exports-file ] [ -d facility ]
[ -P port ] [ -R dirname ] [ -Fhlnprstv ] [ --debug facil�
ity ] [ --exports-file=file ] [ --foreground ] [ --help ]
[ --allow-non-root ] [ --re-export ] [ --pub�
lic-root dirname ] [ --no-spoof-trace ] [ --port port ]
[ --log-transfers ] [ --version ] [ numservers ]
but it looks to be buggy:
numcopies
This is an experimental feature that lets you run
several instances of nfsd in parallel. When given a
value of numcopies greater than one, nfsd will fork
as many times as specified by this value. However,
the servers do not share a common file handle
cache, which makes certain file operations impossi�
ble.
For this reason, nfsd will disallow all write oper�
ations when invoked with this option. Although this
is very limiting, this feature may still prove use�
ful for exporting public FTP areas or Usenet News
spools.
I use this feature on both solaris and FreeBSD, what I'd do
in the init script is something like:
NUMSERVERS=15
[..]
start-stop-daemon --start --oknodo --quiet --exec /usr/sbin/rpc.nfsd --
$NUMSERVERS
(the above is probably line-wrapped so be sure its not linewrapped on your end)
beyond that, you'll need the kernel-space server most likely it is
much faster then the userspace server. Which of course means you may
have to alter the filesystem layout of the server.
