If your /tmp is on a memory-based filesystem like mfs or tmpfs, then
yes.  If it's just a regular disk-based filesystem, probably not.

That's unlikely; writing to a memory-based filesystem shouldn't cause
any more load than writing to an NFS filesystem.

How is that increasing NFS traffic?  You're still doing exactly the same
operations, just in a different directory.  In any event, that would
only help if the problem were disk contention on the NFS server, which
it isn't.
