Have you disabled the agent cache? Otherwise, headers should be cached, and entering a summary is bounded almost completely by CPU generating the actual summary buffer. For nnimap, Gnus wants to get fresh flags from the server, which can take time if the server is slow, but it doesn't normally download any headers or the like. For nntp, I think the entire delay is in summary buffer generation.
