Kleine Gute Nacht Geschichte:

I’d like to share a customer story that got the networking nerds here at Netgate (and we are proud to be labeled as such) pretty excited. Our sales team received an email from someone interested in using TNSR software for a home lab. The email suggested he needed something that could handle up to 100 Gbps throughput across his internal network, and scale up to 40 Gbps to support a future upgrade from his ISP.

The home lab belongs to Torstein Steine, an SAP software engineer who leverages his lab for software development, self-hosted cloud storage, and even a hosted game server for his friends.
Torstein had been working on building his dream network for some time. With four managed switches to support up to 100 GbE network transfer speeds, he needed a high-performance router that could be maintained and upgraded with off-the-shelf components. He was tired of paying for “closed box” products that quickly became obsolete.
Prior to contacting Netgate, Torstein tried to make two other routers work in his environment.

He outgrew his first router, a Ubiquiti EdgeRouter Pro 8, as he upgraded his network stack from 1 GbE to 10 Gbe, then to 40 GbE, and eventually 100 GbE. Torstein couldn’t get more than 1 Gbps of throughput with the EdgeRouter, nor could it saturate his upgraded switch connections. He considered going up to the EdgeRouter Infinity, but decided against that option as he would never be able to get more than 10 Gbps of throughput, and it can’t be upgraded.

Next, he gave a VyOS Router a shot. At least VyOS addressed his desire to use a software-based solution that he could self-install on a server. Unfortunately, it didn’t fare much better. While it was faster than the Ubiquiti EdgeRouter, it still fell short on performance. Like any good software engineer, Torstein poked around in search of a workaround to the throughput issue. As he explained, “Something seemed off with the VyOS solution. I was only able to get 70 Gbps of total throughput across multiple network cards, and could never fully saturate a 40 Gbps connection across my VLANs due to CPU overhead.” He came up empty handed.

The search for a suitable software-based solution continued. While investigating DPDK open-source networking, Torstein stumbled upon Netgate’s TNSR software. TNSR uses both DPDK and VPP. That sounded interesting, so he shot us an email with a few questions and a list of his requirements:

Das Projekt könnte euch auch interessieren. Er baut einen Router mit einem Ryzen 5 5600X. Seine 10GBIT NAT lokal tests scheinen schon mal viel versprechend. Mal schauen wie es dann aussieht mit 25Gbit

@killerkappi jetzt wollt ich gerade den selben Link hier rein feuern, bei nixcraft gesehen?

@konkretor Bei Hackernews war der link auch auf Platz 1 glaub ich :-)

Ich bin damals bei der recherche über den mikrotik auf sein twitter und dadurch auf sein blog gestossen. Und da er angedroht hat einen eigenbau router zu machen pinge ich gelegentlich sein blog an

Nimm die Mellanox Karte. Die sind unkompliziert und manchen kaum zicken.

Hoffe mal das passt hier zu dem Thema. Ich würde gerne Testen, ob mein jetziger Homeserver die 25 Gbit routen kann bzw was der hinbekommt durch ein Nat.
Ich hätte folgendes Szenario überlegt.

• 2Port SFP28 karte in homeserver und PC
• 2 DAC kabel dazwischen
• Pf sense auf Router
• Portweiterleitung auf PC
• Auf PC server und client von jperf unter linux auf die 2 ports verteilt

Habt ihr eine bessere Idee? Habe leider nur die zwei geräte die nicht Laptops sind
