Gemessen: Netzwerkdurchsatz diverser Raspis (Ergänzung: USB-NIC an Laptop mit USB 2 und 3) bearbeitet von Fritzbox-Benutzer 04.10.2019 18:41 Die realistischen Datendurchsätze schwanken ziemlich stark und weisen erheblich von den teils "sportlich" anmutenden Herstellerangaben ab. **Umstände der Messung** * Alle Raspis und die Gegenstelle ("IPERF-Server") hängen an einem guten Switch (nicht an der Fritzbox, die ist aber WLAN-AP), das Netzwerk hat zum Messzeitpunkt kaum parallele Last, auch die Prozessoren "ideln". * Das LAN kann 1 GBit, alle Kabel sind CAT 5e oder CAT 6, IPERF-Server ist ein AMD Ryzen 7 2700 Eight-Core Processor (mit 1 GBit-NIC) und hängt am LAN. * OS ist durchweg Linux. * Die Messungen wurden wiederholt und hatten besonders bei den unerwartet geringen Durchsätzen starke Abweichungen um bis zu 50% des gezeigten Wertes: Raspberry Pi 2 Model B Rev 1.1 via LAN ~~~ $ lshw 2>&1 | grep 'product:' | head -n1;
