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.
