Hi All, I am doing routing performance test using smartbits tester. The traffic is pumped by smartapplications (that runs on smartbits). I see that the routing goes on for some time, then the fps(pps) value starts dropping until it becomes zero. This is for rates less than 10Mb/s and packet size 64 bytes. But same thing happens with various packet sizes such as 256, 1024 etc. When debugging I see that the function ip_finish_output2 (in net/ipv4/ip_output.c) calls hh->hh_output. At the start of the test hh->hh_output calls dev_queue_xmit so routing goes on fine. Then suddenly it starts calling neigh_resolve_output after which pps value starts gradually decreasing and it finally reaches zero. If anyone has solved similar problem or knows what causes this problem, please let me know. Any suggestion is welcome.
