That may or may not be true - the original post said that 'after 50K
plus child nodes retrieval is taking ~15 seconds'. I obviously added a
note that this - with the current JCR implementations - is expected.

What you consider a limitation is something that I personally consider
an implementation constraint - if you want to use JCR it's something
that you need to take into account.

That being said, Oak is expected to perform much better with flat
hierarchies, as long as the child nodes are not sortable. So you might
want to try this as well. Just be careful since nt:unstructured does
have orderable child nodes so you're better off using something like
oak:unstructured.

Thanks,

Robert
