You know how 'smart' I'm not, mL - but ... Jeff Geerling does a lot of testing 
and the Pi CAN do 1Gbps... theres also 'OpenWRT' thats a slimmed down pfSense 
type software...

Another route is to get a Pi 4 Compute Module, and a backplain [small, Pi 
sized] that has PCI... then you can plug any PCI net card in and... viola. 

It IS capable, but.. it IS also an Arm SBC. They are awesome... its CAPABLE - 
but the shortcomings, yes. Checkout OpenWRT - I think YOU'LL instantly know 
more about it than me. :P 

PS, I'm getting the 'normal' 30Mb/sec NAS speeds thru my NFS on a Pi 4 now... I 























































































































































































































































































































































































































































































































































































































































































































































love them for what they are. NOW, if I picked another SBC or... my new server, 
with faster PCI HDD connections... the Pi has a few bottlenecks is what I mean 
to say. 

And yea, my PiBoy DMG is specially built PCBs that does what I think Deon has 
built using his own different HATs. I really love it - and have modified the 
Raspberry Pi OS to fully work on it; so not only do I have the 
Gameboy/MAME/C=/Amiga games - I have a Linux box, Pi 4 powered, thats fully 
portable. I love it.
