The problem is that ISP provided kit is built to a price, so will tend to have a more aenemic processor. Shaping high bandwidth needs CPU cycles, or better yet, hardware offloading.
Funnily enough, I've just got a firmware applied to my cable connection with Virgin Media in the UK that mitigates the Puma 6 issue on their provided DOCSIS 3 modem - it's eliminated buffer bloat as well, which is a nice side effect.
People are listening, Docsis 3.1 includes active queue management for instance, which goes a long way to preventing the issue.
- StudentStuff 8y agoNote that the firmware update doesn't fix the issue (which is Intel failed to put much cache on their chips to save $$), but merely helps to lessen the impact of Intel's shoddy hardware engineering. I would still replace your modem with a non-Intel modem ASAP if you want good performance.

- philjohn 8y agoVirgin Media in the UK don't allow third party modems. I've run a lot of tests since the update, and it's definitely on a par now with my old FTTC connection, jiter especially is much improved.
