#Speedify raspberry pi router full
Under 2W at idle is pretty respectable for a full gigabit router! Conclusion Power consumption offers a similar story: the DFRobot board (which, admittedly, has many fewer features and I/O to support!) uses half the power as the Seeed board: On the DFRobot board, I didn't see any indication the CPU was getting overloaded even under longer stress tests with a full gigabit of data going through.Īnd that overhead is most apparent when sending through small packets-using hping, the Seeed board could only handle half the packets per second of the DFRobot board.

On the Seeed board, the overhead of the USB 3.0 bus and hardware and driver limitations cause interrupts to stall on one CPU core (as measured by atop), and the router can't put through more than around 700 Mbps. Testing method and full results in these GitHub issues: DFRobot board, Seeed board. How much of a difference does that make? Well, it's pretty noticeable: For the DFRobot board, there is a Realtek 8111h Gigabit NIC directly attached to the PCIe lane.For the Seeed board, there is a USB 3.0 chip on the PCI Express bus, and a Microchip LAN7800 USB to Gigabit Ethernet NIC on that bus.The first adapter on each board is supplied by the built-in Broadcom gigabit NIC on the Compute Module itself, but the second one is routed through the Pi's PCI Express bus. The major difference was the architecture of the second Gigabit adapter. I ran three simple benchmarks to get a feel for the performance of the two boards-and the main thing I wanted to test was whether either would bottleneck a gigabit network connection. I'm hoping to build a better Pi WiFi 6E router using Intel's AX210 chip, but that's a project for later this year! Benchmarks WiFi Access Point performance using the built-in 802.11ac chip over SPI is not amazing, though-I could only route around 60 Mbps through the Pi under ideal conditions.
I was able to get all OpenWRT's functionality working well, though to get WiFi working, I had to employ a few hacky workarounds. With Pi OS, both boards will work out of the box with both ports, but then you'd have to set up all the routing functionality by hand. That is, unless this pull request gets merged in someday. Currently, for the Seeed board, you have to manually compile a version of OpenWRT to work with the LAN7800 USB to Ethernet bridge chip on the board.

OpenWRT is about to release a new version compatible with the Pi 4-but that doesn't mean everything will work perfectly on the Compute Module 4 out of the box.ĭFRobot offers a customized OpenWRT image download on their Wiki, but Seeed does not. It really is a tiny router! Click the image to see the full video review of these boards. I have an entire video dedicated to reviewing these two tiny router boards on my YouTube channel, but I'll provide a top-level summary and the benchmarks in this post. Look at the benchmarks further down this post to see what kind of difference that architecture shift made. Plus, with the freedom to access the Pi's x1 PCI Express lane directly, DFRobot's board attaches the second Gigabit NIC directly to the bus, instead of through a USB 3.0 controller, like Seeed Studios did.

These boards are a huge upgrade from any typical Pi 4 model B multi-port router solution, since you not only have half the required device footprint, you also get two ports side-by-side and don't need an extra USB Gigabit network dongle hanging off a USB 3.0 port! The boards are tiny, and even with the Compute Module 4 installed, they are incredibly small-take a look at the entire assembled DFRobot unit, complete with a Raspberry Pi attached: Well, after months of delays due to part shortages, both DFRobot and Seeed Studios have come out with their 2-port Gigabit router board designs, and I was happy to receive a sample of each for testing: Since I started testing various PCI Express cards on the Raspberry Pi Compute Module 4, I've been excited to see what new kinds of custom networking devices people would come up with.
