A 10 Gbps network is MUCH slower than even the smallest oldest PCIe slot you have. So cramming the GPUs in any old slot that’ll fit is a much better option than distributing it over multiple PCs.

I’ve started using this method in the past weeks and it mostly does what I want it to do: https://github.com/eriksjolund/podman-caddy-socket-activation/

The difference might be HTTP vs HTTPS. On a Pi the extra CPU load to properly encrypt the HTTPS stream is probably significant.

Oh I agree with your post, but I was responding to Valmond who used different criteria.

You can have all three of those, but you won’t get great performance. The Samsung QVO SATA drives are a great example. I wouldn’t use those for an OS drive but they’re fantastic for NAS or media use.
