Problem, doubt with pvfs performance x nfs performance

On all of my tests write files using MPI_File_write to a current NFS volume
is faster than write to PVFS2..
For example, when i increase the number os threads, the bandwith decreases
in both PVFS2 and NFS.
NFS in the examples have been 20 times faster than PVFS2.
Is it correct?
I am using a single computer. In 2 computers the results of PVFS2 is slower
than using one. Am i doing something wrong to measure band?
I am not using too, pVFS2 kernell module, i am using it by MPI IO and MPI
