Can one have too many subscriptions? (lemmy.ml)

Just from a performance perspective, when your feed is being retrieved, I can only presume that the more communities you're subscribed too the more intensive the query is?

At some point does it not get prohibitive? Is there a limit on the number of communites one can subscribe to.

If true, I see this as a good reason for user created multi or meta-communities. This way, I can look at a feed of only a subset of communities at a time which should lessen the load on the server, and also be a better interface because I honestly don't want all of the communities I'm interested in being fed into a single feed.

Even the person to person blocking is taking into consideration with that query. Lemmy's SQL output isn't well optimized for caching, it puts a lot of work on PostgreSQL to customize these views. It is only users who are not logged-in that would get a repeatable query.
