Comparing large JSON files

[FHantke]

Hi and thanks for the great library.
My use case is that I compare DOM trees that are represented as JSON files to find the difference between two similar webpages. Unfortunately, I have problems comparing two large JSON files (>300K) as the comparison never comes to an end (I stopped after 10 minutes).

I'm not sure whether this is due to a bug in the code and/or due to the complexity of the JSON files. While debugging a bit, I realized that many elements are compared multiple times with the same element (or also themselves). For instance the following element from diff1.json when compared to diff2.json (Example files).

diff1["childNodes"][0]["childNodes"][1]["childNodes"][29]["childNodes"][18]["childNodes"][0]["childNodes"][0]["childNodes"][1]["childNodes"][0]["childNodes"][1]["childNodes"][1]["childNodes"][0]["childNodes"][0]["childNodes"][2]["childNodes"][40]["childNodes"][0]
{'nodeName': '#text',
 'nodeValue': 'Tienda Kindle',
 'childNodes': [],
 'attributes': {}}

Is there any option in the library to compare large JSONs or do you have any recommendation how to approach this use case?
Thank you!

To give another example, I have two files about 200K each and did a command line comparison with argument -i 2 and it completed in about four minutes. The data is not complex: two properties, one being an array of objects containing two properties: int and a short string.
