I think the details you've omitted mean there's not enough information 
there to actually come to any conclusions! :-)

What distro on the clients and servers ?

What kernel versions ?

What does /proc/mounts say on the clients ?

What is underlying the IP network - 1 gigE, 10 gigE, Infiniband, 
Myrinet, Quadrics, quantum carrier pigeons ? 

What is the MTU ?

What is the file system type on the NFS server that you export (ext3, 
XFS, JFS, etc) ?

What... is the air-speed velocity of an unladen swallow?  :-)
