Remember a given btrfs filesystem is not necessarily a backup
destination for data from one source.
It can be, say, 30 or 60 daily snapshots, plus several monthly, for each
data source * number of data sources.
So while it probably will make a difference (5000 snapshots from one
source, vs 5000 snapshots made from many sources) for balance times, I
wouldn't call a large number of snapshots that unusual.
