My impression has always been that load average is not only about processes wanting CPU, but processes blocked on file IO. I also have the impression that nfsd is not async and that it has one outstanding (local disk) IO request per thread. So I would be looking at what's going on with the disk, and it would not surprise me if it's just that with a bunch clients, one can ask for IO than can be done. It would also not surprise me if there were nfs code problems.
