Getting low latency traffic shaping to work in a robust and reliable
way above say ~100Mbps is still a challenge even for relatively recent router
SoCs. Modern multicore SoCs upped the ante in the things-to-look-out for area
by adding CPU power-saving (especially frequency scaling) and load distribution
over CPUs to the mix... Now even something like a raspberry pi 4B with an
additional well-selected USB3 gigabit ethernet dongle (costing less than 100
EUR all in all) will allow cake up to 1/1 Gbps but still requires careful
configuration to do so. No idea whether an archer 20 will do (not even sure
what model that is, here in Germany I see either an C20 or an AX20 but no plain
unadorned 20). If you should try OpenWrt on that thing, the OpenWrt forum is a
good place to ask for configuration advice for specific models (will obviously
not help if you stick to the manufacturer's firmware).
