Traditional QoS performance

[RMerlin]

How would I test for that? SQM is definitely working as I can cap my speeds and it sorts out a lot of the bufferbloat according to dslreports

Not quite sure, you'd have to ask the Asuswrt-Merlin addon devs who worked with Cake as to how they could determine that it wasn't working properly with NAT acceleration enabled.

It's also possible that Marvel does not do flow caching but only employs other techniques to speed up NAT throughput. I'm not familiar with their architecture.

With the WRT32X I've been testing the NAT acceleration options under Firewall and packet steering. They've been off up until now.

That would explain why Cake is working then. Packet steering can significantly improve throughput without needing NAT acceleration like Broadcom uses.

Above without SQM. Hardware NAT Acceleration turned on (no idea if it does anything with WRT32X, it's off by default) and Packet Steering on, which is also off by default.

Above with SQM and the rest enabled.

Above with everything disabled.

Last but not least. Everything on with tweaked SQM settings.
