I can't speak directly to the question you're posing, but I'd like to point out that groups may get a *lot* bigger than that. If Gnus (and Courier imapd, but never mind) were efficient enough I would have an IMAP group with 99,000 messages in it. They aren't, so I split it up by month, and some of them still have order of 10,000 messages. zw
