Hi Anthony, I for one have not tried netperf, so not sure why it’s not working. Assuming it is directly using epoll/select, i.e., no libevent/ev it should work unless it uses a weird threading model. So, it might be worth investigating why it’s crashing.
Do you need both server and client to use vpp. If not, maybe try nginx + vpp and run wrk/ab or any other tool on the client side. Another option would be to extend our home grown vcl test apps to measure latency. See the vcl client and server apps here [1].
