I haven't run into a situation where RAM was a limit I cared much about for many years. If you rely on hamstrung VPS's, perhaps, but RAM is cheap. The servers we buy at work rarely have less than 32GB these days, and most can take 384GB or more. A couple can take up to 768GB.

If anything, I work hard to put more stuff in RAM to avoid hitting disk, as even though we have SSD's in all our new servers, disk IO is still inevitably where we hit limits first, followed by CPU. Running out of memory is a rare event, and when it is it is consistently an indication of a bug.
