Why would anyone not think a Sparc server could host a web site?

An old IBM PC or even a Commodore 64 can host a web site. I think there’s a few online. I’ve seen them before.

I’ve seen a lot of younger “cloud native” age developers who have these insane distorted ideas about how much power is needed to do simple things. You’d be shocked at how much traffic a modern mid range laptop can handle with efficient software. The Ethernet card you can plug into it would probably be the bottleneck, since I’m not sure if they make USB-C cards faster than 5gbps.

A mid range laptop will also handle hundreds of gigs in a SQL database just fine.

If the mid range laptop happens to have a Thunderbolt/USB4 port there are a number of Thunderbolt adapters built around Mellanox ConnectX-4 Lx SFP28 NICs.
