[Wireshark-dev] Capturing 10GbE on a Linux laptop?
Hi folks, Last year using my Cubro EX2+ I managed to capture around 600MB/s on my Lenovo P51 laptop. My P51 has a Thunderbolt 3 interface and has two 1TB NVMe storage devices that are capable of 2+GBps write speeds. I was aggregating multiple 1GbE interfaces into one of the 10GbE interfaces and then using a 10GbE to Thunderbolt 3 adapter. I had two Windows laptops and two OSX 10 laptops driving the load and interestingly the Apple laptops were generating more load than the Windows laptops via SMB2. My question is: Is there a Linux laptop out there that can handle that load. I have looked at System 76 and Librem but it does not seem they are capable of handling the load. -- Regards, Richard Sharpe (何以解憂?唯有杜康。--曹操)(传说杜康是酒的发明者) ___ Sent via:Wireshark-dev mailing list Archives:https://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://www.wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-requ...@wireshark.org?subject=unsubscribe

Hi Richard, I know there are some USB-C 10G network adapters (and the ProfiShark 10G, of course), but I haven't tested any of them. Writing that much data to disk is something I do with small portable servers (about the size of a small shoe box) with a FPGA based capture card.

I have tested one or two of them. They run warm to hot but seem to work. In my tests I used NVMe and at that time only had 1TB spare on the laptop I was using (on a second NVMe card), but it was fast enough for about 500-600MB/s. Now you can get 4TB NVMe or even 8TB NVMe (although you would pay $849 for 4TB.) However, you need Thunderbolt 3 and it seems that very few Linux laptops have that. System 76 has one or two (the Adder WS, for example.) The Librem laptops do not. Lenovo has one on it P51 and two on the P53. I used a NetGear GS110EMX to generate the traffic (with multiple devices plugged into it and mirroring all traffic to the 10GBe port(s).) > Writing that much data to disk is > something I do with small portable servers (about the size of a small shoe > box) > with a FPGA based capture card.
