Hey! That did it. I hadn't tried that before because I had tried using the
tcp option to mount and the docs suggested that that would do more than
reducing the block size. Besides, the man page didn't give the defaults and
I was uncomfortable changing something when I didn't know from what.
So, why does this fix it? It seems to me that it should have worked anyway.
This feels rather fragile. I doubt that it is hardware related because I dad
tried it on the other ethernet interface in the machine which was on a
completely different network than the one I am on now.
What is the implication of smaller read and write size? Will I necessarily
take a performance hit?
