Hi, I'm looking for some guidance on the efficiency of requesting individual
articles by message-id compared to group and article number.  For a server
such as INN, does finding an article from its message-id impose extra load?

When I display a thread I need to get all the articles in it. I'm
wondering about
spreading the load of this across multiple nntp servers.  However they would
have different article numbering, so I would need to request each article
by its message-id.  Is this practical, or would it impose an unreasonable
load on the servers?

It is reasonable to fetch articles by Message-ID.
NNTP's "NEWNEWS" command is designed to work that way.
