[K12OSN] slow NFS

[Peter Hartmann]

I'm having an nfs problem at least...  On a desktop machine that's
authenticating to the k12ltsp/smbldap server it takes for ever to log
in.  Getent passwd takes 14 seconds to return the smbldap users.  Top
command takes at least 10 seconds to start.

Here's good example of the difference in speed with local vs. nfs
mouted directories:

[localuser at smart1ltsp ~]$ time dd if=/dev/zero of=testfile bs=16k count=16384
16384+0 records in
16384+0 records out
268435456 bytes (268 MB) copied, 8.26981 seconds, 32.5 MB/s

real    0m8.367s
user    0m0.025s
sys     0m0.818s
[localuser at smart1ltsp ~]$ cd /home/Commonfolder/
[localuser at smart1ltsp Commonfolder]$  time dd if=/dev/zero of=testfile
bs=16k count=16384
16384+0 records in
16384+0 records out
268435456 bytes (268 MB) copied, 23.9771 seconds, 11.2 MB/s

real    0m24.018s
user    0m0.016s
sys     0m2.291s

I'm not sure if it's it an auth problem or nfs or both.  I have 4
bonded nics on a Dell switch (close proximity too) with no troubles
can someone help improve the performance?
Thanks, Peter
