Since we're talking about this--what ways are there to optimize the
transmission? I have two Linux machines with NE2000 compatible cards. They
currently make about 85 KB/s through NFS... (I transferred a 10 MB file,
and it took about 123 seconds.) The cards are directly connected. Only two
hosts on the network.
Is there a way to speed up things? Am I doing something wrong? (Looks
like, with 7.3% of what is supposed to be the maximum performance...)

TIA,
