How to use iperf3 in multi-thread mode for 10Gps+ Ethernet testing

iperf3 10GbE multi thread test

With 10GbE becoming more widespread and often found in entry-level hardware, the CPU may become the bottleneck, so I’ll explain how to use iperf3 in multi-thread mode to fully saturate the 10GbE bandwidth even with a system based on a relatively low-end multi-core processor.

For this tutorial, I use two iKOOCORE R2 Max mini PCs with two 10GbE interfaces each and an Intel N100 quad-core processor running an OpenWrt fork (QWRT) and Proxmox VE (Debian) respectively. I will show how I can fully saturate the 10GbE interfaces using multithreading, but not with a typical iperf3 single-core test.

HUNSN RJ42 and RJ43 Intel N150 fanless network appliances and mini PCs come with four 2.5GbE ports, four video outputs

HUNSN RJ42 Intel N150 Network Appliance

We’ve previously seen the new Intel N150 “Twin Lake” processor in mini PCs such as Beelink EQ14 and ASUS NUC 14 Essential among others, but the new quad-core CPU is now also found in HUNSN RJ42 and RJ43 fanless network appliances with four 2.5GbE RJ45 ports. They also double as mini PCs with multiple video outputs and USB ports. The mini PCs ship with up to 32GB RAM and 512GB of storage, support four independent displays through HDMI, DisplayPort, and USB-C interfaces, and offer five USB Type-A ports for expansion. The HUNSN RJ42 and RJ43 offer a similar set of features as previous Intel N100 network appliances with 2.5GbE ports such as the iKOOLCORE R2 and INCTEL N100, but with a slightly faster Intel N150 “Alder Lake-N Refresh” or “Twin Lake” processor thanks to higher clock speeds, and extra interfaces. HUNSN RJ42/RJ43 specifications: SoC – Intel Processor N150 quad-core “Twin […]

Khadas Mind 2 AI Maker Kit – An Intel Core Ultra 7 258V “Lunar Lake” mini PC for developers

Khadas Mind 2 AI PC Dev Kit

Khadas recently announced the Mind 2 mini PC with an Intel Core 5 or 7 “Meteor Lake” mini PC. But the company is prepping the launch of another similar device called the “Khadas Mind 2 AI Maker Kit  Dev Workstation” or “Intel Core Ultra Processor (Series 2) AI PC Dev Kit” with a 15th Gen Intel Core Ultra 7 258V “Lunar Lake” processor offering up to 115 TOPS of AI performance. I’ll just call it “Khadas Mind 2 AI Maker Kit” for shorts. The system ships with 32GB RAM and a 1TB SSD, and Khadas says the new system is designed specifically for developers working on AI PC applications, but apart from the faster SoC, it comes with similar features as the Mind 2. This includes HDMI 2.0 video output, two 40Gbps USB4 ports, Wi-Fi 6E (802.11ax), and Bluetooth 5.3 connectivity, as well as two USB 3.2 Gen2 Type-A ports […]

Sfera Labs Strato Pi Max DIN rail industrial controllers now support the Raspberry Pi Compute Module 5

Raspberry Pi Compute Module 5 industrial controllers

The Raspberry Pi Compute Module 5 (CM5) was launched at the end of last month, and we are starting to see companies slowly announce upgraded CM4 designs. Yesterday, we wrote about EDATEC ED-IPC3100 DIN-Rail mountable industrial computers, and today, we’ll cover Sfera Labs’ addition of the Raspberry Pi Compute Module 5 to their Strato Pi Max DIN rail industrial controllers. The controllers still feature a gigabit Ethernet port, a 10/100M Ethernet port, two USB 2.0 ports, a Raspberry Pi RP2040 microcontroller for power management and boot sequence control, and support expansion modules for up to sixteen RS-485 or RS-422 ports, four CAN V2.0B ports, digital and analog I/O, and more. Strato Pi Max specifications (as of December 2024): Base Module Raspberry Pi Compute Module 5 Raspberry Pi Compute Module 4 Zymbit SCM options. Microcontroller – Raspberry RP2040 dual ARM Cortex-M0+ at 133 MHz. Storage – eMMC, microSD (dual for XL), M.2 PCIe […]

Raspberry Pi 500 review with Raspberry Pi Monitor and teardown

Raspberry Pi 500 review with Monitor Speaker

The Raspberry Pi 500 keyboard PC is just out along with the 15.6-inch Raspberry Pi Monitor and received samples from Raspberry Pi for review a few days ago.  I’ve had time to play with both, so in this review, I’ll go through an unboxing of the kit I received and report my experience with both the keyboard PC and monitor. Unboxing I received two packages. The first one with the Raspberry Pi Monitor, and the second with a Raspberry Pi 500 (UK layout), a 27W USB-C power adapter, and a micro HDMI to HDMI cable. So not quite a full Raspberry Pi 500 Desktop Kit since there’s no mouse and beginner’s manual but close to it. Let’s start with the keyboard PC. The bottom side of the package has some specs and a logo for the keyboard layout, in this case “UK”. There’s only the keyboard PC in the package. […]

Raspberry Pi 500 keyboard PC launched together with 15.6-inch Raspberry Pi Monitor

Raspberry Pi 500 and Monitor

The Raspberry Pi 500 keyboard PC is now available with the guts of a Raspberry Pi 5 including a Broadcom BCM2712 quad-core Cortex-A76 SoC, 8GB LPDDR4x and a 32GB microSD pre-loaded with Raspberry Pi OS. But the company also took the opportunity to launch the 15.6-inch Raspberry Pi Monitor that was first showcased at Embedded World 2024. That means Raspberry Pi launched 22 products this year including kits, and we’re promised that would be the last launch for 2024! But Pi fans can expect a small surprise in the first half of January… Raspberry Pi 500 keyboard PC Raspberry Pi 500 specifications: SoC – Broadcom BCM2712 CPU – Quad-core 64-bit Arm Cortex-A76 processor @ 2.4GHz GPU – VideoCore VII GPU with support for OpenGL ES 3.1 graphics, Vulkan 1.2 VPU – 4Kp60 HEVC decoder System Memory – 8GB LPDDR4X-4267 SDRAM Storage – 32GB microSD card preloaded with Raspberry Pi OS […]
