Sorry for the noob question I am considering Ubiquiti EdgeRouter since it
has good reviews, SQM and is on the list here
https://www.bufferbloat.net/projects/bloat/wiki/What_can_I_do_about_Bufferbloat/
I see the need to configure your typical up/down link capacity for it to
work properly.
Is this the norm? I perhaps naively assumed these smart algorithms would
work on queue size regardless of link speed - which can vary.
My ISP varies on upload between 4-8mbps so IIRC that means I need to tune
SQM at the low end, but this means when performance is better it will still
be capped... or have I misunderstood and it will still utilise the
additional capacity on good days?

Thanks.

Didn't you just ask this question?

There were several replies including links to auto-tuning scripts.
