10GB/s routing fanless for $500 ?

I just came across this today :
https://www.alibaba.com/product-detail/OEM-OPNsense-Pfsense-firewall-hardware-mini_62100677126.html?spm=a2700.wholesale.deiletai6.1.76201d58MNU2sm
Pricing on such devices looks real, another one here :
https://www.alibaba.com/product-detail/POE-mini-pc-intel-3855U-CPU_62015422259.html?spm=a2700.wholesale.deiletai6.5.5e906d6chvJ1Gm

I'm still completely new to SFP+ and actually to anything above 1BG/s (home user...)
But I'm wondering if something like this could actually route so much traffic... I do have 5Gb/s fiber connection coming from my ISP, could probably plug the SFP(+?) connector in there and find a direct attached or BaseT to go to my NAS/server and workstation...

But it somehow seems too good to be true... Especially with a Celeron 3855U... But with an i7 7600U ?

Do you think it can sustain over 5Gb/s from my desktop to my server or to my ISP (provided I manage to use this instead of my ISP modem if the ISP is nice enough to pass along the PPOE settings...) ?

Or is such a device realy not suited for such speeds and it exists only to have the SFP connector to be able to bridge longer distances in the industrial world but not to sustain high bandwidth ?

Thanks for any insight

You need to differentiate routing from firewalling (especially with IDS/IPS, Proxy and stuff).
I wouldn't doubt that this device is capable of plain routing 10Gbps but I doubt it will have high bandwidth with firewalling and stuff in place.
Even with the i7 7600U (CPU was released 4 years ago) it won't be able to do saturate a 10Gbps line, depending on IDS/IPS etc. This i7 is only a 2 core cpu with hyperthreading.
For the price still not a bad choice though.
I prefer boxes with IPMI/BMC on-board.

Thanks a lot for the reply!
So I guess with suricata disabled this would still greatly outperform my current routeur which has only 1GB/s NIC...
Not a big fan of SFP for the home I fear it'll be years before I can profit of this on more devices but I haven't found a similar device with 2,5GB/s or 5GB/s using home standard RJ45 in similar prices...

Thanks again, have a nice day.
