Not OP, but looking at our metrics the first response I picked was a load for a blog article. It does 3 db queries (because it is not very well optimized, the blog is not super high traffic), one for the tenant, one for the actual article and finally one for the (image of the) team member who wrote the article.
This endpoint runs in ~26 milliseconds average, 6 ms of which are in ActiveRecord and 19 ms are in ActionController. I assume the remaining millisecond is an artifact of rounding in the monitoring and/or some overhead in other bits of the framework. Most other endpoints are pretty similar, though there are some internal queries for reporting etc that take much longer of course.
