[ECOS] how to increase network performance?

[Srinivas rao <ch_srinivas321 at yahoo dot co dot in>]

Hi All,

          I tested Network Performance Test on my board using nc_test_master and nc_test_slave test cases and its working fine but the performance is not good. 
Please help me how to increase network performance ?
