I do not see anything wrong in the stats below: ip4 forwarding is dominated by pps not bandwidth so when packet size decrease, pps increase. You seem to be limited to ~620Kpps per worker, which is low, but this depends from your hardware and configuration. Just to be sure: you are not running a debug image, right? You can also check 'show err' output to see why packets are dropped, this should give you some insight. > (mixed traffic in varying sizes (usually larger than 64 bytes) packets) > > Thread 1 vpp_wk_0
