Fedora14: Very very slow NFS write performance

[Don Quixote de la Mancha]

Are you using userspace NFS or the kernel NFS?  The kernel NFS
_should_ be faster.

If you are using the userspace NFS, the strace command will show all
the system calls it makes.  Run strace against the NFS daemon and
untar a small tarball with just a few files, otherwise it will spew
mountains of logs.

strace -f will trace child processes in the event that the daemon
forks when you use it.
