Description

You may see that the speed dropped when using custom TCP window sizes, which I guess it’s because of the mismatch window sizes internally in bridge, but I don’t give much attention to this as the default TCP size works fine. Due to the shortage of the chip that has a unique built-in MAC address, FriendlyElec no longer list the R4S board with a unique MAC address for retail sales. My workstation is a Ryzen 2700X and the Ethernet is an onboard interface on the ASRock Fatal1ty X470 Gaming K4 motherboard with the latest firmware at this date. The Nanopi-R4S’s case is very compact and it’s only a bit bigger than its predecessor Nanopi-R2S, but also includes more horse power under the hood.

Someone could argue here that the switch should be placed after the LAN and not before WAN, because WAN is meant to be connected to your ADSL/VDSL router. The “echo” results in “-bash: /sys/devices/system/cpu/cpufreq/policy0/scaling_governor: No such file or directory” and trying to mkdir policy0 in “mkdir: cannot create directory ‘policy0’: Operation not permitted”. I then inserted the card into NanoPi R4S, connected Ethernet cables to the WAN and LAN ports, and powered it using MINIX NEO P2 USB-C power adapter. I even refuse to waste my time reading network tests reports if the report suggests that nobody knows how affinity was done nor which modules were loaded. Also the board I’ve received came with an aluminum case, which has a dual purpose, for housing -of course- and it’s also used to cool down the CPU.From the above table you can see that the new Nanopi-R4S is faster than R2S especially when it comes to UDP data transfers. ports that can interface with external hard drives, 4G modules, USB HD cameras, USB WiFi modules etc.

You can control packet size either with iperf’s ‘-M’ option (to set MSS), or by setting MTU at interface level for iperf client and server (https://www. Kind of weird that they decided to provide a proper Linux distribution with mostly outdated kernel sources while they managed to create an OpenWRT image with the latest mainline.

You will have to manual change the source link to get updated pkgs if your using image made by sleepwalker as he have created a new repo to maintain all bsd builds. The single-board computer comes with a MicroSD slot for external storage of up to 128GB and has no onboard eMMC (Embedded Multimedia Controller). They are only at, build and ship, Debian testing / Arch / Manjaro / Suse Tumbleweed / Kali / Gentoo support quality level! For a reference point, my RPi4 does cake/piece_of_cake on an asymmetric 900000 kbit/s down/300000 kbit/s with no buffer bloat (waveform test).

I was able to import it and create a very basic 3D model only exposing the most important things like clearance holes, pin headers and the important chips by simply creating extruded bosses with height measurements I did with my caliper gauge. I believe the increased consumption is due to the fact that the docker daemon runs in the background (OpenWRT) and uses 20-30% of the CPU at idle. Most of the driver’s job is just accessing memory, and that’s not worse in little cores than big ones. The R4S uses the RK3399 SoC, has two Gbps Ethernet ports, microSD storage, and either 1GB DDR3 or 4GB LPDDR4. I just want to see some figures at this state of software as, with the right setting, those can be improved by 30-40% (from my experience with routing on NEO4 with various USB to Ethernet adapters).Wow, if the name sounds familiar, it may be because you've read the author's seminal paper [1] on web page segmentation. At the heart of NanoPi R4S, FriendlyELEC has chosen Rockchip RK3399 hexa-core processor with dual-core Cortex-A72 up to 2.
