Description
I've read the btrbk FAQ but it didn't answer my only question. How many snapshots of a subvolume does BTRFS let the user create before disk performance begins to suffer?
Last time I looked into this, online sources were telling me to avoid creating more than 20 or so snapshots per subvolume to avoid degraded performance. Is that no longer the case?
Has anyone done some decent research / tests regarding this using a recent kernel?

Research direction
Start with the btrbk FAQ and the question's cited concern about snapshot counts on recent kernels. Research or run tests on BTRFS subvolume snapshot counts and disk performance, then document a clear, evidence-based answer in the FAQ.
