Today I got my hands on the new Raspberry Pi 3 Model B+. One of the most notable new features is Gigabit Ethernet. Given that the Raspberry Pi still uses the USB 2 interface for the Ethernet controller, I was curious to see what kind of bandwidth it could handle (I know the MagPi already published this, but I wanted some independent numbers). To do that, I setup a simple experiment:
- One Raspberry Pi 3 Model B+
- One Raspberry Pi 3 Model B
- A single SD card with the latest Raspbian (that I moved between the boxes)
- One Gigabit switch
- A Linux box to perform the test from (wired to the network)
For the test, I used the classic network testing tool iperf
.
So how did it go? Turns out that it is almost three times as fast. It is nowhere near full Gigabit speed, but it is still a nice performance improvement.
The data is in Mbits/sec. You can find the raw numbers here.
