Nnimap used to do its own NOV caching which was (usually) more efficient than the Agent caching (specifically -- nnimap only retrieve NOV headers in blocks, leaving no gaps in the .overview file, this means it sometimes does too much work, but it can pay this back by needing less round trips and probably loading the server less). But this is now probably disabled: (defvoo nnimap-nov-is-evil gnus-agent Although this should really be backend dependent, and only be disabled on agentized backends. I remember trying to optimize the nntp.el code too, but the NNTP command trace doesn't display the received data so it was a little difficult to debug.
