cp rcp xfer time difference

[Robert McGraw]

1. OVERVIEW - We have a Sun 4/280 server running SunOS 4.0.1 and a
Sun4/110 client running SunOS 4.0.1. The Sun4/110 has a 327 MB drive
attached. 

2. QUESTION - When I copy (cp) a file from the 4/110 physical disk to the
4/280 physical disk, the file speed is about 55 Kb/sec. If I remote copy
(rcp) a from from the 4/110 to the 4/280 I get transfer speed of 300
Kb/sec. Why is there a big difference in xfer time between the "cp" and
"rcp" over the NFS.
