Hardware Platform: SABRE SD
Software :Android 4.4.2 Kernel:3.0.35
I want to develop the high-speed wireless card driver on this platform.
At first I want to check the max performance of the udp sending in this platform. So I make a simple socket application in C, just sending the 7900 bytes size udp packet in one single thread as fast as possible through the loopback device. But I found that the performance can only reach about 800Mbps, and CPU utilization is just 25%.
My question is how to increate the UDP sending performance in one single thread?
