That's interesting; we didn't notice much extra slowdown for 6
processor machine running 6 realignment jobs on a 100 Mbs network.
This was an Alpha machine with processors running at rough equivalent
of 2 GHz Pentiums I suppose. Did you do any direct timings by any
chance, comparing NFS to local hard disk? Did you saturate the NFS
bandwidth?
Best,
