"name": "TP-Link Archer C7 v2"

I only get ~200Mbits/sec.

That is around the figure you can expect from a 720 MHz mips 74Kc single core CPU (QCA9558) - and in practice your traffic is very jagged and laggy at the top of that throughput.

@systemcrash

If I run:

iperf -s -D ; iperf3 -c 127.0.0.1

I get about 500Mbits/sec

That's a totally meaningless figure, you're effectively only testing the RAM bandwidth here, which has no direct impact on the routing abilities of your device (data coming on WAN, being processed by netfilter, router, NATed, going out to LAN).

So you have 500Mbps-1Gbps fiber and need a router READ THIS FIRST

It's such a frequently asked question over the last few years that we really need a post we can point people to. So your cable company rolled out 500Mbps or 1Gbps download speeds, or you have 1Gbps symmetric fiber (GPON/EPON) from ATT or Centurylink or Orange or whoever. You realize your old all in one router from 2009 is not up to the task of handling this, but hey by now stuff should be cheap and available that will handle your new fiber connection right? So you want advice about a router for…

applies to your situation, ath79 is far beyond its abilities for that.

[these two posts don't belong into the 22.03.3 announcement thread, as it's not specific to this release at all - earlier releases (21.02.x, 19.06.x, …) can't get any more out of this hardware either - just that half a decade ago, fewer users had the WAN speeds to even notice these hardware limits]
