The choice between 15000 and 16384 is the choice between the delivered data
rate to the filesystem, or the data rate at the network interface. There is
about a 10% overhead in TCP/IP for ftp frames including ACK's. 15KBytes/sec
results in about 128kbps at the network interface, and 16.4KBytes/sec results
in about 144kbps at the network interface.
Read the difference between limit-rate and limit-total-rate if you plan to
issue multiple background ftp sessions or use parallel > 1 for a mirror command.
have fun,
John
