Could someone point me to some documenta= tion which gives performance gain of round trip time or packet processing t= ime in terms of time, say, usecs? Also, what is the tool that is widely used for performance benchmarking in= the context of DPDK (with and without user-space TCP/IP stack)? Thanks, -Sujith
