http://www.dslreports.com/speedtest?table=1&focus=65097a33d775b1d6bc531084ca8d8211 this is the link for the long duration tests, although most of them were capped under a download of 70.5 Mb/s, some of the more recent ones were uncapped and only capped by the SQM scripts from the router itself.

Unfortunatel this link does not work for me. But have a look at the first post of https://forum.openwrt.org/t/sqm-qos-recommended-settings-for-the-dslreports-speedtest-bufferbloat-testing/2803 to get recommendations how to link dslreports results for this forum (this also includes recommendations for configuring that speedtest).

@Woofer

I’m not sure what you mean by the triple-isolate,

Cake defaults to triple-isolate mode, where it tries to control connection hogging for both internal and external hosts, but for your use case I believe strict per internal IP fairness should be easier to predict.

For your testing I would recommend you add the following to your /etc/config/sqm (or if option lines with the same names already exist just change the values as shown here)
option linklayer 'ethernet'
option overhead '18'
option qdisc 'cake'
option script 'layer_cake.qos'
option iqdisc_opts 'nat dual-dsthost mpu 64'
option eqdisc_opts 'nat dual-srchost mpu 64'
option linklayer_adaptation_mechanism 'cake'

@Woofer

And I can go ahead and set the MPU to 64, but the page said “only use this part if your MTU > 1500” and i’ve tried doing tests for finding if my isp will allow mtu’s greater than 1500 and found that they all fail, 1500-28 was the biggest i could manage with the custom command for the size in cmd, sorry i forget what it’s called at the moment.

Yes, that help text is a bit obsolete...
