Having trouble achieving 1Gbit UDP throughput

Question

For UDP packets with a payload less then 1470, is it possible to achieve 1Gbit throughput? Due to the small packet size, there should be some bottlenecks in achieving such t

Answer 1

What type of network connection are you using? If you're using a 1000BaseTx/Fx link, don't expect more than 80% throughput with maximum sized packets. As your packet size decreases, the overhead for spacing, synchronization, Ethernet headers, IP headers and UDP headers increases in relation to the payload and therefore degrades your maximum throughput even more.
