6455用NDK开发速度能到多少M/s，用的ET1011C

c6455是千兆以太网，应该能达到60M。请看下面的benchmark。

跟PHY芯片有关吗？我用的ET1011C，测试的时候，就调用 ndk的send函数，上位机接收数，算出来的速度就到25MB/s，请问你觉着修改那些方面可以提高速度呢？

是否有参考过上面链接里的这篇文档， cache, buffer size可以提高性能。

 我设置 rc = 81920*10   然后发送的时候

while(1)

{

bytes= send(s ,(char*) buff_ddr ,81920*5 ,0)

}

我循环向上位机发送，用360网速测试，测出来的最大也就30MB/s
