Streams.EstimatedSize is invoked for every append to a data object builder. This method ended up consuming 44% of total CPU time due to it iterating over every label in every stream every call. We can precompute the size of all labels when a new stream is added, skipping over the iteration. This will make the method several orders of magnitude cheaper with a large streams section.
