I'm surprised that a websearch hasn't taken me straight to the answer for this question. Following links through a dozen pages on the Atlassian site hasn't, either.
What are the system requirements for JIRA? How much RAM and disc space does it require, for a small setup (half a dozen users and projects, fairly light usage)?
Thanks. I actually found that page first, too, but the answers were buried behind a collapsing link, below the fold, past half a dozen other links that don't do anything useful in either browser I've tried (e.g. Clicking 'Server-side requirements for production' doesn't do anything at all).
John unravelled all that in his answer, so I'm awarding him credit.
