Archer A7 v5 wifi throughput test results using iperf

Installing and Using OpenWrt
1

I have tested Archer A7 v5 using 7/7/2019 openwrt-ath79-generic-tplink_archer-a7-v5-squashfs-factory (DISTRIB_REVISION='r10440-8ef6240fa6') and

I have run traffic between 2 linux machines with iperf3. Client connected to Archer, server on 1Gbit switch, Archer on the same 1Gb switch.

Start Server: iperf3 -sD
Run on Client: iperf3 -c "$SERVER_IP" -i10 -Z -P6 -t60
Monitor on Router (opkg install procps-ng-vmstat): vmstat 3 or top -d 3

  1. Test of NAT throughput. OpenWRT in default router/NAT mode, client connected to archer over 1Gbit wire.
    Result: ~400Mbit/sec with close to 100% CPU consumed by sirq or "software interrupts"

  2. Test of WiFi throughput without NAT. OpenWRT in dumbAP mode, client connected to archer over 80Mhz wide 5Ghz radio from 2 meters distance.
    Result: ~350Mbit/sec with same bottleneck: 100% CPU consumed by sirq or "software interrupts"

PS: Looking for suggestions of a OpenWRT supported router that can NAT 1Gbit or close to it :slight_smile:
