Question on ISR 4321, right now our device is setup for 100000 kb/s throughput, however when testing iperf on our private WAN connection (which is 100mb/s) we are only getting 42mbps. We are likely hitting a throughput limit on this device? Topology is
Server(iperf)-->switch-->ISR-->WAN MPLS--->ASR-->Switch-->Server (iperf)
