Time), the proportion of time spent by the three is about 250: 30: 1, which is based on the packet size of bytes.
The larger the ratio of the three, the longer the transmission (or receipt) and DMA packets are the time bottlenecks.
During interrupt processing, it takes a little longer to "New packets arrive" than "packet transfer completed.
