841v11 - FASTDv18 - 841v11 iperf tests


#1

Analog zu den wireguard tests Lede Test - Wireguard und blanko Durchsatz TP841Nv11.1 und BUG haben wir auch nochmal fastd getestet, hier der Vollständigkeit halber noch erwähnt (und in traveler-english)

to our tests on tp-link841-v11 we tried to test fastd for direct comparison

again, the setup is
laptop(iperf3) > tplink841v11 < FASTDv18 salsa2012 > tplink841v11 < laptop(iperf3)

actual lede , fastdv18 both default - both build today
TP-link841v11 is pretty cheap . 560 . 650Mhz CPU 4 MB Flash, 32 MB RAM

main result is that wireguard seem to be a little little faster (TCP iperf)
15.5 Mbit for wireguard
14 Mbit for fastd

but we observe on fastd also that we can crash the system with udp, (like we reported before for wireguard)
on both systems throwing much udp traffic in the tunnel make the first tp-link unresponsive with load of 2.5 and much higher, pretty soon oomkiller kill random processes due to out-of-memory

so maybe it is not that wireguard has a specific problem, than there is a general problem with lots of udp traffic

following the TCP iperf, the udp iperf and the crashlog (dmesg)

noch zu erwähnen das der Vergleich zu wireguard nicht ganz fair ist, da mit salsa2012 ein vereinfachter cypher benutzt wird. Die Szenarien entsprechen zwar denen die man real einsetzt, um die beiden nebeneinander zu vergleichen müsste man eher salsa20 testen.

Der 841 hat seit der Version v10 einen 650MHz Chip

@Tarnatos youre right ! :slight_smile:
but according to TP-Link TL-WR841ND [OpenWrt Wiki] its 560 Mhz …

und viel wichtiger

udp stürzt ab sobald man wesentlich mehr als 50Mbit drüberschickt.
