[ECOS] Low network throughput using DHCP

Hi,

Had someone experienced that the networking performance
dropped down dramatically while using DHCP? My CPU
is a 50MHz MIPS, and the result of tcp_echo is around
4Mbps when using static IP, but dropped down to about
0.4Mbps when using DHCP. Another aspect is that the
tftp_client_test failed almost every times to get a file of
20K bytes via TFTP when using DHCP, but the same test
program worked well by using static IP.

Any suggestions?

Thanks.
Xavier
