    It seems to me that your performance test will reflect disk access times just as much as network
    performance.  I tried it with a 3675 accessing its own two large drives (a 515 and a 470) using
    NFILE and found the following performance:
Note that 3670s have a much faster SMD access time than the 50. Part of the
reason is software, part of the reason is that the channel is 16 bits wide
on the L machines, and only 8 bits wide on the N machines.

So, 367x's make faster file servers than 3650s (if you can afford the
