Ich habe bei mir diverse Server unter Proxmox laufen. Neben FHEM läuft dort auch Nextcloud. Das Problem ist nun, dass der Traffic dorthin aus dem Internet viel langsamer ist, als meine DSL-Leitung liefert. Lt. Speedtest liegt Download bei ca. 80 Mbit und Upload bei ca. 27 Mbit.
Ich habe jetzt mal direkt auf dem Proxmox-Server einen iperf3 -s laufen, gegen den man den Traffic von außen messen kann (den Port 5201 für iperf3 habe ich kurzfristig für Tests geöffnet)
Meine dynamische IP lautet heute 188.126.184.48
Wenn ich nun im gleichen Netz dagegen teste, bekomme ich meine volle Bandbreite meines LANs:

Mit 1,39 Mbit und 0,608 Mbit bin ich weit davon entfernt meine DSL-Bandbreite zu erreichen.
Hat jemand eine Idee wo das Problem liegt? Meine Vermutung ist, dass es am Provider liegt.
Ich habe den iperf3 server z. Zt. bei mir laufen. Man kann es also heute mit iperf3 -c 188.126.184.48 -V antesten.
Hier mal die Ergebnisse von zwei Testläufen.
Der erste Test ist aus meinem lokalen Netzwerk heraus gelaufen,
der zweite Test von einer Amazon Lightsail Instanz aus Irland.

Ok. Danke für den Test. Also wird meine Bandbreite doch erreicht, je nachdem von wo man testet.
Ich habe auch mal gemessen - Standort Estland, Internetverbindung 100 MBit / 100 MBit:

Danke. Auch hier immerhin noch 25 Mbit. Offenbar wird der maximale Traffic zu mir nach Hause nur direkt von einem großen Hoster erreicht, nicht aber wenn man es von seinem zuhause testet.
