@ummjackson @aral @dominick There are more things going on than just sending 3k requests. For example, if a new user interacts with the post, the profile needs to be "federated", meaning avatar/header/bio/keys/pinned posts need to be copied. Also, media files (avatar/header/pinned media) need to be converted to make sure they have the correct dimensions/format. Also, remote servers can be slow to respond and threads need to wait for a response, that also does causes the process to be slower.
