As previously indicated the problem is not in the 'cat' command but in the
interaction NFS V3/V2. I've used a Sun, mounted a Sun partition on my Alpha,
issued a cd command to this nfs mounted filesystem and the problem is still
there. The Sun runs NFS V2.

As answered by somebody the problem is no more there with 2 NFS V3 computers.

Thanks to everybody for the answers.
