By the way I strongly suggest to follow Thomas around wherever he leaves comments like on cnx-software. I'm ashamed to admit that I was lazy this time, just used their FriendlyWRT build and then debloated. I think some entries mixed smp_afffinity_list and smp_affinity, though I can’t say for sure since it takes time to review it. IMPORTANT AND REMIND not include SD card , you need an SD card to install OS and you also need power by 5V/3A .

It is (apparently) a good hardware platform for developing IoT applications, NAS applications, smart home gateways etc. The first test is to test only the WAN interface, using my workstation which has an onboard GbE interface. FriendlyCore has some issues, and limited information in NanoPi R2S Wiki, so instead let’s try FriendlyWrt, and I flashed rk3399-sd-friendlywrt-5.

For example I prefer to have the WiFi router before the WAN and some of my devices after the LAN, so the devices connected with before WAN don’t have access to the LAN devices via the bridge interface. As far as I know raspberyy pi4b's achieve gigabit shaping with mostly large MTU-sized packets, not sure what their actual packet per second limit is, but for most normal use cases this is somewhat moot, but it would be interesting to tests as likely the same PPS-limit would apply for 2. In many cases, the device isn’t fully supported by the “vanilla” Linux kernel, so you’re either stuck with some old kernel build or, by using a newer mainline kernel, you miss out on some features and performance optimizations that haven’t been upstreamed yet. Such numbers which are extremely sensitive to latency and per-packet processing time mean nothing with no precise context around.

Most of the driver’s job is just accessing memory, and that’s not worse in little cores than big ones.To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Biggest problem with SQM on the R4S at gigabit line rate is that the lower-speed cores aren't quite up to the task of handling interrupts and nowhere near powerful enough for line-rate shaping. The WAN interface is getting an IP from the DHCP router which is also connected on the GbE switch and the Nanopi-RxS runs it’s own DHCP server for the bridge interface which is the range of 192. Finally, I decided to power cycle the board, it got an IP address, and I could finally access it via SSH using the default pi/pi credentials.
