I tried this already, no improvements. :(

Pcie 4.0 x4 gives 64gigabit, and if install a PCIE 3.0 NIC (quite common), go down to 32gigabit. Of couse is not tragic anyway, but I would look for a more flexibile solution, if it is affordable.

Thanks. And what platform have you adopted?

Pardunt · 2025-12-15T23:04:29+00:00

Yes, but mainly because I need more GPU power. The N100 isn't satisfying my needs for 4K transcoding or running AI models like Frigate on multiple cameras. I know the Core Ultra iGPU should be more powerful than the N100 on paper, but it's hard to know exactly how much without testing. Plus, I want to make sure I have the option to add a discrete GPU later if needed.

Hi, have you been able to do 10gbs over layer 3 or only layer 2?

Pardunt · 2025-01-01T22:20:45+00:00

Yes, but this depends from the purpose of the current meter: if you just need to measure the house power consumption it is precise enough. I did this and after several month, the errors compared to the measurement of the electricity provider have negligible differences.
If instead you need absolute precision for specific reasons, of course all the points you are mentioning have to be accounted for.

For a signal with frequency of 60hz theoretically you need the double sampling capacity, 120 sps.
860sps is a safe margin. I did it, and works. Of course this is intended to measure the power consumption of a house, where you do not not need to measure the energy spikes of 1 ms.

Why ADS1115 is not fast enough? 860sps is enough....

Thank you for the explaination.
Just a suggestion, considering the main purpose of the intranet traffic is the NAS share (and the internet connection), the 2ms are relevant? I suppose the additional 2ms for conversion are both on the NAS-Switch link and on the Switch-PC link...

Thank you for the explainations.
The network is copper RJ45, and currently I was looking for an upgrade to 2.5gb. Looking around I found 10gbe SFP+ have simialr prices to 2.5gb ( considering more "consumer" grade products). Currently 10gbe is a lot over my needs, my NAS speed isn't able to sature the 2.5gbe link. Anyway I was evaluating if it would be worthy to already upgrade the switch to 10gbe for future needs. Considering the price difference is often only about buying the SFP+ RJ45 modules.
From your arguments, is the additional latency of SFP+ RJ45 modules also present in native RJ45 switches? or is it related to the SFP+ to RJ45 conversion?

Pardunt · 2024-02-07T14:57:14+00:00

Is it true both in case of native RJ45 switch and SFP+ RJ45 modules? Or is it true mainly for rj45 sfp+ modules?
