[ECOS] The performance of ethernet driver and freebsd stack is not good

[Jack]

Hi all:
  I am new at ecos os. I am working at Ethernet driver and tcp/ip stack.
  But I find the performance of driver and stack is not good enough.
  I test them by nc_test_master and nc_test_slave including in ecos package.
  TCP_echo item shows the through is about 12Mb/s.
  And at the same platform(ARM7 TDMI at 80 MHZ), the through is about 32 Mb/s
  on uClinux os.
  The problem let the through so low will be the stack or Ethernet driver?
  Anyone can help me to figure out this problem?
  Thanks.

Jack
