Hi Jean-Félix, > Query _changes with a simple filter, include_docs=true, since=0 : ~ 95s
I would say that the problem here is "since=0". I see _changes as a queue between the database and something else. Imagine what would mean restarting the queue in a car factory from the very beginning. This would be terribly long, however there are indeed very few occasions you have to do that. I think you should replace your filter on _changes by a view on update time. Regards, Aurélien
