[CentOS] Optimizing NFS over loopback

I have set up a local NFS server and I'm accessing it over the localhost 
interface.  Here is my /etc/exports file:

/data/vm 127.0.0.1(rw,no_root_squash,async,no_acl,wdelay,no_subtree_check)
/data/iso 127.0.0.1(ro,no_root_squash,async,no_acl,wdelay,no_subtree_check)

Here is the relevant /etc/fstab entry

/dev/sda3/data   ext3    defaults12

Things are working, but seem pretty slow.  I'm getting about 10mb/sec.  
I was wondering where the bottleneck could be?  Is there a way to 
optimize the NFS service for better throughput?

I am accessing over 127.0.0.1

Thanks in advance,

Russ
