> My WAN is connected at 1000 full duplex. My bandwidth is 300 mbps
download and 100 mbps upload. The device can go up to 190-200 mbps
download at 100% CPU after patching. It was able to do 180-190 mbps
before, but there were no problems with latency and packets dropped at the
router level on the network interface.

I think there might also be a problem with QoS on PPPoE devices. QoS on
bare devices seems to be much better than on PPPoE on top of an ethernet
device.
Latency and QoS seems worse for upload than for download. Pinging a remote
host without QoS on the router from another machine on the LAN during the
download phase of speedtest.net yields ping reply times of 3-8ms. Pinging
from the same machine during an upload yields ping reply times of 6-50ms
at 100mbps without any downstream traffic.
