You're rewriting a simple program (cp) to cover for a lack of capability in the kernel. There's no reason that I can't do a read(1048576) and have the kernel turn that into as many reads as possible -- in this case, for 8k, 2^7 reads. Oh, and, it is likely that when we issue that many or more reads, we want a flow controlled network. Just guessing :-) ron
