Both of these mount points are on the same netapp.  Client 
is a CentOS4.3 (RHEL4 u3) machine.

time dd if=/dev/zero of=/nfs/.test bs=1024 count=250000  # 
real  0m27.267s

time dd if=/dev/zero of=/cifs/.test bs=1024 count=250000 # 
real 11m14.242s

Any thoughts or theories as to why CIFS is so much slower 
than NFS?  I have tried different rsize/wsize options even 
and no difference.
