Description:
While downloading the repository from Mongo, the indexing job has to discard
hidden entries. This is being done by a call to
{{{}NodeStateUtils.isHiddenPath(){}}}. This call is rather expensive, as it
creates an iterator over the path segments, which requires creating a new
string for each path segment. As the indexing job has to check every entry to
verify if it is hidden, this creates a significant overhead.
The implementation of checking for hidden paths can be replaced by a simple
search for {{"/:"}} in the string representing the path, which requires no
object allocation and should therefore be much faster.
