Are you sure you are measuring L1 rate? This is common problem in tooling that only L2 is reported.
64.0/(8+64+12) == 76.2% L2 rate, when L1 rate is 100% 90.0/(8+90+12) == 81.8% L2 rate, when L1 rate is 100% Also if you are sending wirerate on ingress and putting it on pseudowire, you're increasing packet size, so you must send smaller packets.
