I assume you saw the video with Plunkett the RPF put out ( https://youtu.be/yiHgmNBOzkc https://youtu.be/yiHgmNBOzkc specifically interesting at 10:45 ) - He mentioned he was testing 10GbE fibre and reached 3.2gbit. Now he goes into absolutely zero detail on that, but I find it interesting you've both hit the same ceiling.
(He also mentioned 390MB/sec write speed to nvme, which is suspiciously close to the same ceiling)
- geerlingguy 6y agoYeah, I think the PCIe link hits a ceiling around there. Note that combining the internal interface with the 4 NIC interfaces, and overclocking to 2.147 GHz got it up to 3.4 total Gbps. So the IRQ interrupts are the main bottleneck when it comes to total network packet throughout.
- jlgaddis 6y agoSince you're also from the midwest, I'll put it in terms you'll understand: :-) > I think the PCIe link hits a ceiling around there. You're trying to shove 10 gallons of shit into a 5-gallon bucket! -- I'm not sure how high you can set the MTU on those Pi's (the Intels should handle 9000) but I'd set them as high as they'll go, if I were you. An MTU of 9000 basically means ~1/6th the interrupts.
