Only those who spend time analyzing just how busy an ‘idle’ network can be know that there are a lot of processes in constant communications with their cloud services. </div><div class="">The challenge are the end users, who only understand the silly ’speed’ metric, and feel anything that lowers that number is a ‘bad’ thing. It takes effort to get even technical users to get it.</div><div class="">But even beyond the basic, the further cuts induced by fairness is the new wrinkle in dealing with widely varying speed test results with isolation enabled on a busy network.</div><div class=""><br class=""></div><div class="">The high density of devices and constant chatter with cloud services means the average home has way more devices and connections than many realize. Keep a note of the number of ‘active connections’ displayed on the OpenWRT overview page, you might be surprised (well, not you Seb ;) )</div><div class=""><br class=""></div><div class="">As an example, on my network, I average 1,000 active connections all day, it rarely drops below 700. And it’s just two WFH professionals and 60+ network devices, not all of which are active at any one time.</div><div class="">I actually run some custom firewall rules to de-prioritize four IoT devices that generate a LOT of traffic to their services. Two of which power panel monitors with real-time updates. This is why my bulk tin on egress has such high traffic.</div><div class=""><br class=""></div><div class="">Since you like to see tc output, here’s the one from my system after nearly a week.</div><div class="">I run four-layer Cake as we do a lot of Zoom calls and our accounts are set up to do the appropriate DSCP marking.</div><div class=""><br class=""></div><div class=""><div style="margin: 0px;
