I also have a Raspberry Pi with 4G and it handles its load perfectly fine.

BUT lack of memory is a well known bottleneck so when I got a Raspberry Pi 5 with double the processing I also doubled the memory to keep it fed. While I haven’t really found a good niche for the new beast yet, if I’m spending money on a faster processor, faster board, why would I limit it by cheaping out on memory.

While we know that Apples memory is much faster than anyone else’s, we also know the entire system is outstanding. If I spend so much on a system with such high throughput, why would I want to cripple it by cheaping out on memory to save a relatively small cost? It’s not that I really have a need but that I’m paying for a beast so it better be able to go beast mode

If you’re transferring files over a socket (like through SMB or SFTP), the receiving end usually has a small buffer, like 64KB. It’ll just pause the stream if it’s receiving data faster than it can push it to disk and the buffer gets full. So usually a file transfer won’t use much memory.

There is some poorly written software that doesn’t do that, though. I ran into a WebDAV server that didn’t do that when I was writing my own server. That’s where you could run into out of memory errors.
