As I saw Jeff Geerlings Website and his iperf Benchmarks of different RPis (Link<\/a>), I wondered how the RPi Zero would perform by using the USB Virtual Ethernet Interface on my Windows 7 x64 PC.<\/p>\n

So I got the latest iperf 2 Version (iPerf 2.0.5-3) from the iperf Website at https:\/\/iperf.fr\/iperf-download.php<\/a>, installed iperf from the Raspbian Jessie Packages and launched the iperf Server on my Windows 7 x64 PC via iperf -s. The PC was attached to an Gigabit Switch via an Gigabit Ethernet Interface - so no bottleneck here.<\/p>\n

Then I started the iperf tests via iperf -c IP -t 20 -i 2<\/code>.
\nAnd these are results:<\/p>\n

60.7 MBit\/s - ok, the RPi Modell B v2.0 got double the RAM (512 MB) than the old version - but that did not have impact on the network speed.<\/p>\n

94.2 Mbits\/s is a good value, the matches with Jeff ones - so I am feeling a bit better after the bad measurements of the RPi 1 B pre\/2.0's...<\/p>\n

Finally - and that does come in as a surprise: I though the Pi Zero - attached via USB Ethernet would give me any value between some Mbit and some really odd numbers - but it closely matches an really solid 100 MBit Interface - so... Thats cool :)! <\/p>\n","protected":false},"excerpt":{"rendered":"
