through out releases on snapshot and now back to latest release, I think there might be a slight regression or perhaps my settings were never the best they could be for my link.. could have sworn i had < 5ms on download on wired test.
Router: RPI 4 64bit
SQM

option download '940000'
option script 'layer_cake_ct.qos'
looking at htop during test, it really only loads one core on the download, however that core is never maxed out. Upload seems to use more cores, also not maxed out.
my link is 1.5gbps down/ 1gbps upload
other notes: eth1 is usb tplink ue300. Using dscp classify. packet steering = enabled, irqbalance = enabled. firewall flow offload for software + hardware = enabled
If any one else has an RPI 4 running their router + 1gb fibre links please share your configuration
