Cake Speeds

[Pocah.H]

I remember hearing that Cake is not very effective about 300MBps. I wonder if this is still true now that we all have faster networks? My network 2.5Gbps and internet is 1.6Gbps.

The problem is the CPU power of these routers, they can't keep up with faster connections as Cake requires hardware NAT to be disabled.

Thank you for the reply.

What would be the best approach to use in place of Cake then?

With 1.6Gbps ISP line try no QoS. Perhaps the best approach.

Thanks for the reply!.
I did some experimenting.
It seems that most of the problems whatever device the router was talking to on the WAN. I have no idea how it controls bandwidth, but it was very messy at lower bandwidths.
At 300Mbps (limited by my ISP), I was getting latency increases off the charts (>250ms) when I approached that 300Mbps limit (>270Mbps).
Cake did great job of reducing the latency bringing it back to <20ms or so.
But at >500Mbps, without Cake, the problems had largely vanished. Latency increases were nominal.
The poor latency performance seems to be down to whatever device was limiting my bandwidth. At 500Mbps and above it performed very well, but below that it was a nightmare.
I am not a network person so forgive me if none of that makes sense!!
