@mgaido91 thanks for the update! I ran some tests locally on my laptop as
well. I didn't see as big a difference as you mentioned in the JIRA, but I did
see a performance improvement, after running several times. The performance
improvement was more pronounced, it seems, when there was a large nested
structure, which I suppose makes sense. I've merged this to master. Thanks
again for the update!---
