As a reminder, noticeable loss of throughput occurs only when = there are a lot of concurrent flows=C2=A0(>16, on my connection).

To my knowledge and testing, ingress mode has been b= ehaving like this from the beginning.
I'm using the old cobalt branch with the version after= ingress mode was implemented.
tc-cake is configured with ingress mod= e and bandwidth 18800Kbit.

Downloading from a server with 2x16 connections= using two aria2c processes, ~35ms ping latency to the server, I get about 1= 8.7 Mbit/s received bytes on the interface (/proc/net/dev).
The remaining gross download rate is about 17.3 Mbit/s.= That also matches the qdisc stats (drops/pkts =3D roughly 8%).
