If i reboot the router is ok ?
No need for that, kione's killall command (killall -9 iperf3) will do it. If for some reason you don't have that command, use "ps w" to get the process ID (the first column) and say "kill -9 xxx" where xxx is the pid.
It's not doing any harm right now, just wasting a small amount of memory.

If there is no routing involved then how come you can add iptables rules that apply to the iperf traffic, mangle the IP addresses, block ports, etc? You could add an iptables rule that redirects the iperf traffic to another host on your network if you wanted - if that's not routing I don't know what is!
Granted it's not processing a lot of rules by default because the first INPUT rule is an ACCEPT for the lo interface, but the packets are going through the same TCP stack and iptables process that actual routed packets traverse so it's a lot more than just a RAM bandwidth test.

Hello,
it seems your are running an ath79 based image?
Mine iperf3 is close to 600mbits on a 9558(oc to over 900mhz, but still your benchmark is way below some posts above).
May I suggest, if you have time, rerun the iperf3 on an ar71xx base image.

Well, isn't that the best time to check all the connected devices against our beloved openwrt routers 
re-calculating and verifying (from time to time) can't hurt.
