To test this theory we turned off encryption and ran again:īoom, Speedify with no encryption puts the Raspberry Pi 4 back to its full 800 Mbps speed. This means the Raspberry Pi CPU needs to do a lot of extra work to encrypt every message, that the Odroid can skip.īut if that’s the case, why isn’t the Raspberry Pi 3 affected? Because its CPU is faster than the USB 2.0 bus. So, Speedify reverted to ChaCha20 encryption in software. But the Raspberry Pis don’t have the optional ARM extensions for AES. Raspberry Pi 4, however, sees a 30% performance drop with Speedify!Ī little bit of poking around quickly reveals something interesting: the Odroid N2 has AES encryption hardware, which Speedify found and used, making encryption nearly “free” for the CPU. The CPU for the Odroid was not maxed out while running the test. In fact, it appears that the Odroid is actually maxing out the Internet connection, and could probably go faster on a different connection. The Odroid and the Raspberry Pi 3 each see a small (less than 5%) performance drop while running Speedify. The Odroid manages to max out the maximum speed that our single iPerf TCP stream can handle.įor our next test, we installed Speedify, with encryption on, and ran iPerf3 right on the device’s CPU: Both Odroid and Raspberry Pi 4 were maxing out the available network bandwidth. One cool new feature that comes with Speedify for Ubuntu and Raspberry Pi OS allows you to use Ethernet or the internal Wi-Fi card to share your bonded connection. We really see how much the Raspberry Pi 4 improved IO performance over the older Pi 3. Just use Speedify for Linux and turn your Raspberry Pi into an advanced VPN router. Neither the Ethernet card nor the CPU is fully loaded, they just can’t shuffle packets back and forth fast enough. The results with the external Ethernet card gets a much better speed, but reaches the limit of the USB 2.0 bus which connects it to the CPU. Its built in 100 Mbps Ethernet card is immediately maxed out. Right off the bat, we see the Raspberry Pi 3 is unable to keep up. This should give about the same results as you would see with a Raspberry Pi 3B+ using built in Ethernet: Because the Raspberry Pi 3B only has a built in 100 Mbps Ethernet card, we ran the test again using a Gigabit USB Ethernet card. Some of the limitations below are with the available network bandwidth and not the devices themselves. Over this Internet connection, the available bandwidth for a single TCP stream to the Nova 2 server was typically around 820 – 850 Mbps. the VPN connection as an Ethernet router that other devices can join. Tests were run using iPerf3 with a single TCP stream against the Northern Virginia #2 Speedify server (without Speedify running for the first test). I share my Speedify connection on Linux via Ethernet (Ubuntu and Raspberry Pi. For the Raspberry Pi 3B additionally we used a USB Ethernet adapter, as the built in Ethernet is limited to 100 Mbps. Thanks in advance for the help.We decided to start simple: each device hooked up via Ethernet to a Verizon Fios Gigabit Internet connection. Has anyone used this system or know what could be causing the issue? I'd really like to use this service to create some redundancy or increase performance. I'm having issues getting my ATEM Mini Pro to speak with this new bonding service and I can't figure out what is causing the issue. You can combine hotspots, wi-fi, and ethernet together to make one good connection for use or use additional connections as redundancy should one fail. I came across a company called Speedify that allows you to bond several internet connections at once to increase reliability and performance. The downside to this is I only have one internet connection active and should I lose connection or not have enough bandwidth I run into issues. I have done several events like this and it seems to do the trick. I will connect my Atem to my MacBook and then share my internet connection to the ATEM so I can live stream. I from time to time use my mobile hotspot to stream online with my ATEM Mini Pro. Hey guys, I'm hoping someone here has used this system or knows how to correct the issue I'm having.
