I need to benchmark different endpoint (not router) network performance with different encapsulations (if_gre, if_gif) and with/without IPsec (including if_ipsec). What is suitable traffic generator/receiver for me? I'm trying to use benchmarks/iperf3, but it consumes questionable amount of CPU in several cases and maybe benchmark becomes limited by user-side CPU consuming, which is bad. I've tried "benchmarks/netperf" — it hangs with non-default window size. I've tried "benchmarks/netperfmeter" — it doesn't work without SCTP in kernel. Please note, that I'm testing endpoint, not a router, so netmap-based packet generators & receivers is no use for me, unfortunately. -- // Lev Serebryakov
